We have used the kzread.infoUgkxOTeIs0vv4_9B5hsmnLsk9r930uDQLu_Y for probably 30 hours with our camper and it’s been great! The noise level is really only noticeable when running the AC and other appliances like the microwave, hair dryer, or coffee pot. It’s not huge like other ones and it has wheels so even at 90lbs, I can move it!

Nice video, as stated before it's nice that someone actually puts numbers onto the system.

I have 9 panels on my flat roof, angled on frames; one row of six and one of three. Initially I was advised to bias them a bit east of due south, to get the most of the early sun. That was fine for five years, but recently I moved the row of three and pointed them west of south. It has improved the situation noticeably, as the angle of the rays gets less efficient on the six, it is improving on the three, charging until around sunset. In some circumstances this will be worth taking into consideration. Saludos from sunny Spain.

Thanks for clarifying and putting down some average numbers! Very helpful.

The great thing about standards is there are so many to choose from.

5 years ago, my power bills were huge, just for 2 people, so I put 5kW on the roof. 10 panels NE and 10 NW. The impact on my bills was so good, I put another 5kW on my shed. I have monitors on both systems so I can see the power curve and check they are working correctly. These systems have now paid for themselves, and over the course of a year, my power bills are zero. I have just paid my winter bill of $400, but I will earn that back over summer plus some. Putting PV on the roof was the best thing I have ever done. I monitor the performance of my systems weekly.

With batteries your storing all the excess Daytime energy for use at night. You can see your electric bill drop to a very small amount or actually zero if your system is sized right.

The inverter measures the output and the 3,900 Wp results in an average yearly energy harvest of 4,000 kWh. The Wp/kWh per year ratio is slightly over 1 which is the best one can do over here. The power output of the panels mid day is about 3,000 W with very seldom peaks of 3,500 W for only a few minutes on a sunny but chilly day in the spring.

For batteries, you have to estimate how long you will be without sunshine, and what power you need to be drawing and for how long you will be taking electricity from the batteries. That will help you size the batteries. Then there's a second part to it, which is how quickly do you want to charge the batteries up? And that determines the power rating of the solar panel installation. And that is going to depend on a number of factors such as: the duration of the periods of sunshine the panels are exposed to in your location, the capacity of the batteries. And the brightness of the sunlight comes into play here. Under cloudy conditions the solar panels will not produce as much power and you may decide to double or triple the power rating of the panels, or even more to compensate, so you still get a suitable charging current to the batteries.

Great presentation. The music is a tad too loud.

In the last 2 years I have only failed to fill my Power Wall 11 times from my generated power, but I do manage it so I use ~2Kwh a day of grid power, because I have a minimum charge/day of $0.35 whether I use the power or not. So if I was only using solar I would have had another hand full of days where I didn’t fill my Power Wall completely.

The grid acts as the battery, everything you put back in the day can be used by business /commerce /other people but the domestic consumer owner gets to take back units at night from electricity provided by coal/nuclear / wind, minus a 5% handling charge. This would reduce the demand for expensive batteries and encourage consumers to invest in solar and take responsibility for their usage in daylight hours, they may want to run a washing machine / fridge etc but not leave the tv idle simply because energy is free. Everyone becomes a producer / provider, thus surplus energy results in lower pricing until a balance point is hit where its not worth the investment, the Holy grail of economics. The competitive nature of man means people will then seek improved panel efficiency or more energy efficient electrical goods. Is simple simple stuff and only held back by putting up stumbling blocks to common sense.

I don't know how much my neighbor paid for roof top solar panels, but he is not getting what he paid for since it isn't pointed toward the sun. If I were to guess, it is 25degrees from ideal direction.

So understanding the technology, and understand what you use it for, puts you at an advantage. For example, I know that I would like to stay cool in the summer... mostly in my bedroom where I can sleep. My bedroom is a 10x10' room with a 9' ceiling. a 5000BTU window A/C would work, or even a 6000BTU would be great. That uses about 500W/hr. So, I would need Solar Panels to cover that range. Or at least a battery to store that power (because I care mostly about the night when I sleep) and Let's say I get about 8 hours of sleep... even 10 hours let's say. So that's 5Kwh for 10 hours. I would need a 6Kwh battery to have the A/C constantly running for all 10 hours. But the AC is probably climate controlled so your room doesn't become an icicle. So Of that 10 hours, it's probably only running about 65-70% of the time, drawing from your battery. So, that means: I would need 3x250w solar panels, + 1x5kw battery, + 1 2kw battery. Santan sells used 250w panels for 50 a piece, 5Kw battery is about 3500 on amazon, and a 2kw inverter is about 200 bucks. I can have a nice cool summer for many summers to come without using any extra electricity from the grid for under 5K. (3500 batter+150 (maybe about 50 of shipping)+200 for inverter+500 for cabling.) Off Grid living baby!

Ok, to export power to the grid requires a higher voltage. For a single phase installation the maximum output voltage is 258V. If the equivalent grid voltage reaches 258V then your inverter will reduce output so as not to exceed 258. So, you can either use the power yourself directly or feed it into batteries.

@ukgroucho

2 жыл бұрын

That's absolute BS - at least here in the UK. You export power when you have excess - at around 240V as that is what the grid is rated at (or SHOULD be). Feeding power to the local 'sub-grid' at the normal voltage will power properties on your 'local' (downstream of your local substation) network. If your grid voltage goes over around 248 - 250V then your inverters shutdown. Why? Because the grid provider has the ability to push the voltage UP to signal that all grid connected PV (and wind etc) systems MUST stop producing as the network is in maintenance mode - they push the voltage high with a low power (amp) load so they can work on / test parts of the network without the risk of frying the staff who are working on it (I have VERY explicit experience of this). The opposite is when the power goes off from the grid - and your inverters shut down (same reason) - they need to be able to work on the grid without getting fried by a bunch of solar generators etc. pumping unexpected power into what is expected to be a safe distribution network. This is why a Tesla Powerwall will disconnect you from the grid when it goes into backup mode..

@@welshe222 So your average daily use is about 16.5 kWh (or 'units' as it is often referred to). I use nearer 20 kWh on average per day. My system is 8.5 KW. Throughout the summer I generate FAR more than I can use on most days - sometimes as much as 50 or more kWh per day - so even though we will try to do high current draw stuff (washing machine, dishwasher, oven etc.) during the day we still export a bunch. This June and July we generated nearly 900 units per month and exported around 40% of it. When we eventually get electric vehicles (one EV and one PHEV ordered but not due until early next year) we will be able to time charging them to make use of that extra stuff we are generating. We were mostly self sufficient from May through to end of September but there were some days when the weather did not co-operate so the Tesla Powerwall was not full charged and ran out overnight (well down to 16% remaining which is the default that it holds onto) so we used a few units overnight. The challenge is that once the days get shorter and the sun gets lower and you get more cloudy days and you start running off the battery earlier in the evening and later in the morning you simply cannot generate enough to run the house (unless you had a HUGE solar array and batteries) - so, for example, yesterday we only generated 6.9kwh, today just over 9kwh, but Monday 19.2.kwh so we were pretty much self sufficient. As we get deeper into Autumn / Winter I know we will have days when we generate pretty much nothing. The 'bigger' picture is what happens over the course of a year. Last year we used 7360 kWh... 31% came directly off the roof, 32% came from the Tesla Powerwall (so generated, stored, used overnight etc.) 37% was off the grid. So 63% self powered. We generated about 7100 kWh. Also worth noting that the Powerwall doubled the amount of power that we generated and were able to use rather than export. Wish I'd added the Powerwall sooner - only had it since January 2021 and the array is nearly 10 years old. To answer your question specifically, you will not be able to (economically) install enough solar PV capacity to eliminate your need to use grid power - unless you drastically cut that 6000kwh number down. Even then there is a balance between having enough generation capacity to run the house / charge a battery to run the house when you are not generating and having so much capacity that you are exporting huge amounts in the summer - a costly path where I suspect the payback would be long. Plugging the energy generation gap in the colder months is the challenge, I have looked at vertical axis wind turbines but I really can't find a product that looks like it's a good fit. OK long answer... if you have more questions then post and I'll try to help.

@malcolmrose3361

Жыл бұрын

It's impossible to give a reliable average - as DS says above - the wattage rating for a panel is in perfect conditions. That panel may perform very differently mounted on your roof, or on my roof because we live in different places and where the panel is mounted makes a big difference. You need to look at things like the direction your roof faces relative to the sun during the day, the pitch of the roof, is there anything that can block the sun like trees etc. All make a big difference to the performance. As does the time of year - in the Winter the days are shorter and the sun doesn't rise so high in the sky (and as the sun shining at 90 degrees to your panel is the ideal, this makes a difference) so even on sunny days in Winter the electricity generated is less than on a sunny day in Summer. I have a 3.15 Kw system in Southern Spain - my average daily production was 13.17 KwH over the year, but this varied from 8.65 KwH per day in January to 18.83 KwH in July - essentially your annual production follows a bell curve with the high in your Summer and low in the Winter - but someone who lives in India might have a different pattern because of their monsoon season. Also you need to remember that these are averages - so if you have an unusually sunny January, or cloudy July that will mess with your numbers. When you look at a property you need to look at which way your roof faces etc. The other thing to think about is how you use your energy - if you are at work all day and your energy usage during the day is low then you will probably be selling a lot of energy back to your supplier - so, financially, how you're treated by them will make a big difference to you. If, on the other hand you're retired or work from home then you'll soon get into the habit of running your appliances in the middle of the day when your solar energy production is at it's highest - or use timers if you're at work.

So how much does a 3Kw solar system produce in a day if you say a 5Kw solar system produces around 20KwH/day?

The main benefit of solar is to use it as it's generated to directly reduce your power bill. In the good old days we'd help people size up a system to match their daytime energy consumption, these days almost everyone sizes up the system based on their 24-hour usage because they will be purchasing a battery within the lifetime of the solar system. The feed-in tariff no longer matters now that we have battery storage, as you say.

@@SolarayEnergy Are you sure that's how it works in WA? I have 20 panels and my Dec bill for 59 days says I exported 1222 kw/h and imported 408kw/h. I am home all day so use power all day , just seems a lot of exported kw/h if I am using the solar as well? Maybe its setup to export everything and then we pay to import it again? it is Government owned Power company lol.

No one is talking about what inverters and the ratio you are using. This matters very much

This video refers to average performances for a 5kW system. You are absolutely right that the inverter plays a big part in performance. We only do installations with Enphase Microinverters or SolarEdge inverters with DC Optimisers as these will help your system perform better than with a regular string inverter.

How could it make more than 5kW? It's always going to be less. You should always be around 1.15:1 DC:AC power.

I have a 4.8 kw solar system, its pretty sufficient for me . With the exception of an A.C which i don't need coz I live in a moderate climate place, I power everything in my house, i..e oven , induction , fridge, rice cooker, washing machine, dish washer, water heater or geyser,etc in daytime and in the night , I used only the Tv, fridge , PC and the led lights . I even charge my electric scooty and also slow charge my electric car on sunny days.

Stupid works both ways. A stupid consumer may buy an overpriced system based on false promises and fail to recognize the lower value received. But another stupid person may be looking at a system priced well, a good value, and have the need, but still not understand or believe good promises, and therefore they don't buy the system that would help them.

You guys are so lucky. In South Africa we get 0c for pumping into the grid :-( How is that for motivating people to go green?! And now they are talking of taxing us per PV panel. Going green is a sin in South Africa. Government even put heavy taxes on all green products that comes into the country.

Feed-in tariffs used to be much higher, but yes - comparatively we are lucky to get one at all! Governments should be making greener products more accessible, not less!

You cannot run a house from a 5kW invertor. Spend the extra money an get at least an 8kW. You only need a huge (over sized 10kW preferably 20kW) lithium battery and a few panels 11 to 15 with a 8kW and thus use 100% of the power produced yourself. But first look at where you can save. Don't listen to people trying to convince you to go Gas? You will never get that money back in a lifetime. Rather use the money for a bigger battery. Get an induction stove, air frier and good induction pots and pans and problem solved. The other secret I will keep for myself. First want to invest in the right company I use very little to no grid power.

Lucky if you get 12 kwh on a constitent time frame

the speaker omitted the only needed facts one would consider in such a project? what is the average 4 member family Kw usage over one year, period? many folks seek an 100% off grid system so his inputs are void for them? there is a balance in solar energy between generation peak power, and usage, peak load, the idea is to keep the well 1/2 full at all times. so how is this carried out? take your electric bill add all 12 months together divide by 12 divide by 30, that is how much electric you use on an average day. whatever that amount is measured in KW that is the key point to build a solar system off of, think of it as a point of beginning . so your collection device a string of solar panels 12 volt run by 48 volt into the all-in-one converter will receive this flow of electrons and manage it as the demand put on your domestic service is used through out the day. the inverter is programmable or set it on auto function meaning the box will channel some energy to the in home grid panel, some will go to the batteries, some may go to the neighborhood grid sold back at a 1/3 your price rate! lol

The average daily power usage for an Australian home is 17kWh. Very few enquiries we receive in metropolitan markets are for off-grid systems. This video is definitely not aimed at off-grid prospects - not many households would find 5kW systems suitable for this purpose.

Just remember when you put a solar system in for your house, unless you willing to pay lots of money, normally the system will help you reduce your power bill not cover it all, so if you normally paid $200 for the power bill. After solar installed, you should see you bill reduced. Still better than nothing.
