The lifetime of a solar panel depends on its quality and age. Generally, the older a solar panel gets, the less efficient it becomes. The majority of modern solar panels come with 20-30 year warranties, which means that they’ll stay at a good efficiency level for at least this long. Some panels can stay efficient for as long as 40 years, while others won’t last this long.
It’s vital to purchase a solar panel system that suits your property. If you’re investing in a solar panel system, it makes the most financial sense to get the biggest one possible. However, whether you can do this or not depends on budget and space.
Here’s an idea of how much roof or ground space you’ll need to install a few different sizes of commercial solar panel system.
Solar panel system size, No. of solar panels, Approximate area required
11kW, 44, 64m²
20kW, 80, 116m²
30kW, 120, 173m²
40kW, 160, 231m²
50kW, 200, 288m²
How much energy a solar panel produces depends on its manufacturer and exposure to the sun. A good-quality solar panel typically has a power output of about 300 watts per hour, but this can vary from about 240 to 360 watts. How much energy your solar panel will produce per day depends on how many hours of unshaded daylight it’s exposed to.
Here’s an idea of how much energy you could expect a large commercial solar panel installation to produce in a year.
Solar panel system size, No. of solar panels, Annual electricity output
11kW, 44, 9,350kW
20kW, 80, 17,000kW
30kW, 120, 25,500kW
40kW, 160, 34,000kW
50kW, 200, 42,500kW
Solar panels are made up of photovoltaic (PV) cells. These cells are made from silicon semiconductors, which absorb sunlight and convert it into electricity.
There are three main types of PV cell: monocrystalline solar cells, polycrystalline solar cells, and thin film solar cells. Monocrystalline cells are usually the most efficient and expensive, and thin film solar cells are the cheapest and least efficient. These are all made from silicone, but are manufactured in different ways.
