The average solar panel installation for a 2,000 square foot residential home will be made up of around 18 to 25 panels. The situation will of course vary by jurisdiction and available incentives, which can also differ depending on the power rating of your solar units.
These numbers are based on the average residential electricity usage of 877 kilowatt-hours (kWh) per month (10,524 kWh per annum). The higher your energy use, the more solar panels you’ll need.
While up to N1,000,000 for an average solar installation might sound like a lot, when you break down the cost per watt of solar installed—system cost divided by solar energy produced—the idea becomes a lot more palatable. And don’t forget, solar panels can last for as long as 25 years, so the savings are cumulative.
Of course, the exact number that you’ll need depends on a whole range of factors, such as where you live, how much sun exposure your house benefits from, your average energy consumption, and how much power your panels can generate. We’ll explore these factors in more detail later.
It’s often the case that customers want to know how many solar panels they’ll need according to the size of their house. This is the wrong approach to take, as what truly matters is how much energy you use. A two-bedroom house can easily use more energy than a three-bedroom house, for example.
HOW MANY SOLAR PANELS DO I NEED TO POWER MY BUSINESS?
We know that the number of solar panels for a home depends on energy consumption—but the number of solar panels your business needs follows this rule too.
The key difference between domestic residential solar installations and commercial solar installations is that commercial installations will be relatively larger. This is because the average medium-sized business uses up to 40,000 kWh of energy per year, which is a lot more than most residential homes, and therefore requires larger solar installations to meet those higher energy demands.
The actual amount of energy a business consumes will depend on factors like:
