You need to determine the size of the solar panel system you want for your home before you consider purchasing it. You can find a number of online tools that will help you determine how many solar panels are needed. The Global Solar Atlas and PVWatts Calculator can help you determine the number of polycrystalline panels that you'll require and how much roof space you need. In general, a 5kW solar system should have 20 polycrystalline panels and require about 45 square metres of roof space. Once your system has been installed, you can expect savings of between 6,000 to 8,000 kWh per annum.
Calculating the size of a 5kW solar system
It is important to take into account the amount of power that you want to produce when calculating how big your solar energy system should be. For example, to produce 1,000 kWh/month, you'll need at minimum five kW. This is equivalent to approximately five square meters of panels.
Besides power output, you also need to consider solar leverage, the advantage of sending electricity back to the grid at high rate times and purchasing it at low rate times. More information about this can be found in our articles Net Metering as well as Current and Future SCE Rates. You want to make sure you choose a system which produces the correct amount of your annual usage. It should not be more expensive than you will earn.
Average size for a 5kw photovoltaic system
Twelve half-cell panels would make up a 5kW system. Each panel would produce approximately 5.4kW power and take up 26 square metres of roof space. A 5kW system of solar panels can generate enough energy for your home on sunny summer days, and it can also provide significant power in winter. The output of the system will depend on the angle and shape of the solar panels. Therefore, a steeper roof in winter will provide more output.
An important consideration is also the annual output of your array. This figure allows you to compare the power output of the system and the power that you use. SCE residential customers typically pay approximately $200 per month for their electricity bills. A 5kW system will cost you less, as it's based on kWh.
Cost of a 5-kw solar system
You can save thousands of money by installing a 5kW solar energy system. On average, you will save $2100 per year on electricity costs and more that $67,000 over 20-years. You must also consider the electricity inflation of 5%. Plus, if you decide to export half of your electricity, you can save another $700 or more in the first year.
You can estimate the total cost of your solar energy system by estimating your energy consumption over a twelve-month period. You can do this by adding up the total amount of electric bills that you have for the past twelve months and then dividing it with twelve to get an estimate of how much energy your home consumes. This figure can be divided by the number and cost of solar panels.
Average electricity production of a 5kw solar system
A 5kw solar system converts solar energy into electricity. It includes 16 photovoltaic panel. Each panel contains 16 solar cells interconnected by wires. The larger the number of panels, the more you can produce electricity. Installing a 5kw solar system can help you reduce your electricity bills by as much as 90%.
A 5kw sunroof system will typically produce 20kWh per day. The system's peak output is between 10 and 2pm. Your location and the amount you receive during the day will also affect the power production.
