About How big a photovoltaic panel should I install for my own home
Statistics showthat most people consume more electricity during the summer and winter, when the A/C or heat is running. If possible, collect your last 12 months of electric bills, then tally up your kWh usage and divide by 12 to get a monthly average.
Next, divide your monthly kWh usage by 30 to estimate your average daily kWh usage. The average American home uses about 900 kWh per month, so we’ll use that in our example: 900 kWh / 30 days = 30 kWh per day .
Sunlight availability affects how much energy your solar panels generate. Use NREL’s GHI maps to see how many sun hours you can expect to get in your location. Below is NREL's map for average annual sun hours in the.
From there, we need to add a bit of overhead to account for inefficiencies and degradation rate of the panels. The output of solar panelsdrops.
Most grid-tie homeowners choose to offset 100% of their energy needs with solar. But it is also possible to start with a smaller system for partial offset. To calculate the size of your solar photovoltaic system, take your daily kWh energy requirement and divide by your peak sun-hours to get the kW output you need.
To calculate the size of your solar photovoltaic system, take your daily kWh energy requirement and divide by your peak sun-hours to get the kW output you need.
Key takeawaysThe average home needs between 15 and 19 solar panels to cover its daily electric usage.You can calculate the number of solar panels you will need with your energy usage, the amount of sunlight you get, and the wattage of the solar panels you choose.

6 FAQs about [How big a photovoltaic panel should I install for my own home ]
How do I calculate the size of a solar photovoltaic system?
To calculate the size of a solar photovoltaic system, first divide your daily kWh energy requirement by your peak sun-hours to get the kW output you need. Then, divide the kW output by the efficiency of your solar panels to get the total number of solar panels for your system.
How many photovoltaic panels do I Need?
The construction and quality of photovoltaic panels can lead to output anywhere from 110 watts to 400 watts. The number of panels you need depends on your total usage requirements and the energy you can obtain from each panel. To calculate the system size you need, begin by converting your daily usage into watts.
How many solar panels can you install on a roof?
The size of your roof may limit how many solar panels you can install. A typical solar installation will need a minimum of 335 square feet of suitable roof space. For reference, an average roof is 1,700 square feet. If your roof can’t fit all the solar panels you need - that’s okay!
Should I add a solar energy system to my roof?
You may be considering the option of adding a solar energy system to your home’s roof or finding another way to harness the sun’s energy. While there’s no one-size-fits-all solar solution, here are some resources that can help you figure out what’s best for you. Consider these questions before you go solar. See the Spanish version here.
Can I install more solar panels than I Need?
Yes, you can install more solar panels than you need to prepare for future electricity usage costs, like charging an electric vehicle or switching to electric appliances. Some utilities have limits on how much a system can be oversized.
Should I hire a company to install a solar panel system?
Before you hire a company to install a solar panel system, it's recommended to calculate your home's electricity usage and PV needs for your area. Determine if you can handle the installation yourself or if hiring a professional is necessary.
