To understand your own energy consumption, a good rule of thumb is to review your total energy usage for the past twelve months in your utility bills. Divide that number by 12 and you'll have an excellent estimate of what you'll need your solar panels to generate each month. To get started, answer the following questions to calculate how many solar panels you need to power your home. On average, how many kilowatt-hours (kWh) do you consume per month? (See your electricity bill) Let us help you create a customized draft of your solar energy for you on your real roof.
To learn more about how much your solar panel system could cost, read on. Now that you have an idea of how many solar panels you need, you can calculate the cost of the solar energy system. A standard solar panel produces around 1.24 kWh per day and costs between 65 and 75 cents per watt. Solar panels from well-known manufacturers cost between one and two dollars (or more) per watt.
Based on the results from the solar panel calculator above, you can multiply the recommended wattage by 65 or 75 cents (or more) to get an approximate cost for all of your solar panels. Thanks to federal tax credits and increased demand, solar installation costs continue to fall, making it more affordable to go green. Installation costs fell more than 70% in the past ten years, says Solar Energy Industries Association. The next step is to evaluate the different options for solar kits and energy systems.

Our warranty does not apply to installations in unsafe structures, non-permitted structures, ground mounts, structural engineering, structures not built according to local building codes and other atypical building designs. This warranty only applies to our standard solar system kits, it does not apply to custom orders or solar systems not designed by our engineers. Can be about 17.5 square feet per panel. Therefore, if you want to purchase 20 panels, you will need approximately 350 square feet of available roof space facing the optimal sunlight direction.
Net metering is how your utility company credits you for producing excess solar energy when the sun shines and then allows you to take advantage of those credits when you use a conventional power grid at night, if you don't store your excess solar energy in a battery storage system. The location of your home isn't something that can change, but it's still important to recognize that your region plays an important role in how efficient solar energy is for you. Photovoltaic (PV) solar panels (most commonly used in residential installations) come in powers ranging from approximately 150 watts to 370 watts per panel, depending on the size and efficiency of the panel (how well a panel is able to convert sunlight into energy) and cell technology. The NEXT STEP, now that you have an estimate for the desired kW, SEE SOLAR KIT SIZES to compare prices, brands and options.
Next, solar energy expert Will White breaks down everything you need to know to calculate how many solar panels you need to power your home. The table below shows how many solar panels you need based on the size of the system, as well as an estimate of how much energy the solar panel will produce. This can be defined as the annual kWh of energy produced per kilowatt of installed solar capacity. Therefore, to install a 6 kW solar panel, which will produce 1000 kWh per month in 5.5 hours of direct sunlight, will force me to buy twenty 300 watt solar panels.
And a micro inverter in each panel can optimize energy conversion at the source, unlike a large inverter mounted on the side of the house. After determining how many kWh of electricity your home consumes per year, you'll want to calculate how many kWh each of your solar panels produces for a year. The best way to determine the ideal location for your home's solar energy system and how many solar panels you need is to get quotes from qualified local solar companies.
