Is A 10kw Solar Power System The Best Size For Me
Choosing a solar system for your home depends on how much power you consume or are likely to consume in the future. For instance, if you are planning to buy an electric car, you will have a higher electricity consumption since you may install a charger for it at home.
If you have a large house with a pool and central air, then you may consume a large amount of power. In this case, the 10kW system may be right for you. If you have low power needs, or have children who will be leaving home in the next few years, 10kW might be overkill.
The best way to calculate the correct size system is to take your last quarterly power bill, divide by 3 to get your month’s power usage in kiloWatts and then divide by 30 days. This will give you your average daily usage. If this is around 35 – 40kW, then a 10Kw solar system might be for you. If it is closer to 20kW, then a 5kW system might be best.
How Many Solar Panels Do I Need Then

Typically, a modern solar panel produces between 250 to 270 watts of peak power in controlled conditions. This is called the nameplate rating, and solar panel wattage varies based on the size and efficiency of your panel. There are plenty of solar calculators, and the brand of solar system you choose probably offers one. That said, there is a simple equation to calculate the amount of kilowatt-hours your solar panel system will produce.
So now that we know you need to produce about 6kW of AC output, we can work backwards to figure out how many solar panels you need. Solar panels produce direct current , and your home runs on alternating current .
Yep, like the band, AC/DC.
Because of physics, there are losses in converting the energy from the sun into DC power, and turning the DC power into AC power. This ratio of AC to DC is called the derate factor, and is typically about .8. This means you convert about 80% of the DC power into AC power.
This continues to improve ever so slightly, but the losses are unavoidable because of physics! So you take the AC amount you need: 6kW and divide by .8 . This means that youll need 30 250Wp solar panels or 27-28 270Wp panels.

Can I Install A 10kw Solar System
In most cases, you can install a 10kW solar system regardless of where you live.
Some distribution areas may limit the amount of solar you can install, while most always limit the amount of inverter capacity you can have. They do go hand in hand though.
If you are single phase home in the most common distribution areas across Australia, to install 10kWs of solar you will need to install an 8kW solar inverter or two 5kW solar inverters. In both of these scenarios the distributor will require the site to have an export limiter of 5kWs.
Export limitation is when the inverter can produce its maximum amount of potential but it can only send a certain amount back to the grid. This is to protect the grids infrastructure.
If you are in a three phase home, in most distribution areas you can install 10kWs of solar with no export limiting.

How Much Power Does A 10kw Solar Power System Produce
A 10kW solar power system produces 40kWh of electricity per day, enough to power two average-sized homes or one large home. An average household in Australia consumes 20kWh to 22kWh of power per day. Therefore, a 10kW solar system is fit for a large house with numerous appliances or a small business of any kind.
If your home is connected to the grid, you will be able to take advantage of a feed-in tariff to send excess power to the grid during the day and draw on it at night. An oversized system will further reduce your power bill as the excess power produced may be more than you draw again at night.

How Many Batteries Do You Really Need
The calculations given above are straightforward enough. But it assumes that you want to store all the power your 10kw system produces in a day.
If you only want to store the excess solar energy produced, subtract the extra amount from the total output.
Example: if you use 30kw a day and the system produces 40kw:
40kw-30kw = 10kw
You need a battery bank that can hold 10000 watts.
10000 / 48 = 208ah10000 / 24 = 416ah10000 / 12 = 833ah
As usual you have to round off to the nearest battery size available. You could get 3 x 100ah 48V batteries, 2 x 250 24V batteries or 3 x 300 2V batteries.
10kw Solar System Battery Backup Power Calculation
Here is another example. Suppose you want to store enough power to last for three days, just in case there is a power failure or winter storm.
If your daily consumption is 30kw, you would need 90kw to cover three daysÃ¢ use.
90kw = 90000 watts
90000 watts / 24V = 2750ah90000 watts / 12V = 7500ah
To meet your daily power consumption over three days, you need about 5 x 400ah 48V batteries. You can use these same steps to calculate how many batteries you will need over a specific period.
Note that these calculations will fill the batteries to their capacity. If this is what you plan to do, understanding discharge rates becomes essential.
