Want to learn more about solar panels, their operation, and installation? Xando Energy answers all your solar power inquiries in Southern Florida!
We address the topic of how many solar panels the typical homeowner needs to power their home below, focusing on South Florida homes but applicable to any property that receives plenty of sunshine.
Geographic location, house size, energy consumption, roof shape, weather, and solar panel efficiency all affect how many solar panels a home needs. Your location affects solar panel energy production by determining sunshine availability.
In this article, we discuss the primary elements that affect how many solar panels you need to power your house.
5 Key Aspects of Calculating Solar Panel Requirements
Solar energy specialists consider the following when calculating solar panel needs:
1. Look Up Mean Monthly Energy Usage
Gather last year’s power invoices to calculate your household’s monthly energy consumption. Your utility provider’s website may allow you to download past bills.
Record the monthly kWh usage from each bill. Divide the monthly data by 12 to get your average monthly energy use in kilowatt-hours (kWh).
2. Compute Daily Energy Usage
Divide the average monthly consumption by 30 days. Due to various month durations, this approach estimates daily energy use quite well.
3. Estimate Solar Energy Generation
Sun energy production depends on sun insolation, measured in kWh/m2/day. To get this information, look at solar insolation maps or databases like the US National Renewable Energy Laboratory (NREL) or the European Commission’s Joint Research Centre’s Photovoltaic Geographical Information System (PVGIS).
Locate yourself on a map, record the sun insolation figure, then multiply your daily energy use by 1,000 to get watt-hours (Wh). Divide this amount by sun insolation to get solar panel capacity.
4. Account for Solar Panel Efficiency
Solar panels typically have 15 to 22 percent efficiency. To account for this fluctuation, divide the solar panel capacity from the previous step by the efficiency factor (given as a decimal, such as 0.20 for 20 percent).
For example, a 5kW system with 20 percent panel efficiency requires 25kW.
5. Calculate the Number of Solar Panels
Start by assessing the new solar panels’ power. Manufacturers or product specifications usually give this information.
Divide the needed capacity by the wattage of each panel to find how many solar panels you need.
For example, if 25 kW is needed and a solar panel contains 300 W, 25,000 W divided by 300 W is 83 solar panels.
Additional Solar Panel Installation Considerations
Remember that the calculations are estimates and may vary based on your home and solar panels. For a more correct evaluation, consult a local solar installation professional for likely outcomes.
The size of the roof, the amount of shade, and the local regulations all affect solar panel installation and system efficacy.
