Solar energy is becoming more popular as people recognise the need for renewable energy that won't harm the planet. Of course the constant increase in energy prices plays a major part in the decision to install solar panels.

Non renewable energy sources such as coal, oil and gas are dwindling fast, so renewable sources such as solar and wind power will become more affordable for home owners, and help to bring the cost of electricity down as demand for them rises.

The initial cost of installing a solar power system can still be very high, so it's a good idea to do some research first to see what's available. You can easily do this online, and search through the many different companies that retail solar panels. Read some of the testimonials, and if they are a local company take a look at some of their work on other properties.

There are many manufacturers of solar panels with varying levels of quality. Generally speaking you will find the best made panels are the most expensive, and the better made product will last for a longer time than those of a lower quality.

However you can get some very good deals without compromising too much on quality. You just have to shop around and see what's available

There are many things you need to take into consideration apart from the maintenance costs, installation and pricing of the solar panels. You need to think about the amount of power that they will provide. Your objective is to pay a lower price for each unit of wattage that the panels are able to produce.

As soon as the sun starts hitting the panel it starts deteriorating or losing some of it's value. If you are considering buying used panels you should bear this in mind. You will still be able to use them effectively for a considerable time though, plus they will be a lot cheaper than buying new photovoltaic solar panels.

If you are on a tight budget then this may be the best option for you.

Cleaning the panels frequently will maximise their effectiveness and lengthen life span. Leaves and dirt can block solar cells reducing their ability to generate power.

You could also consider the idea of making your own solar panels. You don't need to be a diy expert and it could save you hundreds of pounds, There are many books and videos online that will show you with step by step instructions, how to build your own panels.

The most expensive part of a solar panel are the photovoltaic solar cells. These can be bought on ebay at very reasonable prices. Alternatively you can buy broken solar cells and fix them yourself. They will be very cheap to buy and still work ok.

They won't look perfect and may have chipped edges but if you are making your first solar panel this won't matter.

Solar panels will work even on days when there is light cloud. The output won't be as great but it will still provide you with some electricity. You will need a deep cycle battery to store excess power for use after dark, or on very dark and overcast days.
