Pv Panels Explained
Have you ever stopped to think what turns the lights on in your house? What powers your fridge, your washing machine or your personal computer?
The way we produce power has mostly stayed the same over the last century and the price of electricity is always on the rise. The methods of producing the electrical energy we use today are mostly the same ones people used almost a century ago – fossil fuels. Now we’ve all heard about the problems of burning large amounts of coals or oil, but only a handful of people are looking to truly find a solution. A renewable, inexhaustible source of infinite, free energy right above our heads – the Sun. The freedom and independence from the power grid are definitely something everyone wants to obtain. This goal has never been closer.
Solar panels provide a clean, waste-free, low-maintenance source of power that is guaranteed never to expire. The costs of these photovoltaic systems (PV panels for short) is plummeting, which is all the more reason to install them on your home. They give a sort of elegant look to your house’s roof, but that’s nothing compared to the money they’ll save you. A roof system of 100kW can be in the price-range of 2 euros/watt. This may sound expensive, but this system gives you complete electrical independence, and will pay for itself in around ten years. Not to mention the waste-free power that those rapidly melting icebergs will definitely appreciate. Solar panels, however, won’t be a good solution to your power issues if you live in a place with no sunlight. Before deciding to purchase, look at a map of global solar potential. This will give you a rough estimate of the effectiveness of panels in your location. It’s not all sunshine with solar panels, though.
A photovoltaic system that supplies continuous power usually consists of additional elements such as large batteries and DC to AC inverters for connecting to your power grid. The panels don’t have high maintenance costs themselves, but are easily damaged, so an insurance policy is something you’ll surely want to take a look at. The cost of an entire photovoltaic system may be overwhelming, even with the substantially lower prices than those from 10 years ago.Solar panels, however, can be used in other ways than just to produce electricity. You can use a smaller array of panels to just keep a reservoir of water always hot. The larger systems aren’t for you if you don’t have a large space or roof to spread them on.
In conclusion, solar panels are a great source of alternate energy today, and will definitely be the energy source for the future. They’re clean, low maintenance, and environment-friendly, they just still seem to be too expensive for most people.
