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
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.
Solar energy comes from the sun. Solar panels absorb sunlight, and convert it into electricity. This can be used to power heating systems, lighting and appliances. You can also get solar thermal systems, which use solar energy to warm hot water.
Solar energy is a type of renewable energy, because sunlight is considered to be in unlimited supply.
