What Parts are needed for Solar Panel Kits?

Whether you are looking to buy a fully installed kit, or alternatively looking to fit a solar panel kit to your house yourself you need to know what work will be happening and what the parts are. Many people buy all of the big bulky bits and forget about all of small parts.

We are going to give you a guide of the larger parts and also the smaller obscure parts you will undoubtedly forget and help you save a few pounds at the same time!

Solar Panels

These are the most obvious things you need - but one thing you need to do is work out what size system you need - and also how big your roof is! Many people simply fill the roof to the rafters with the biggest solar panels they can get on there, and this is all well and good with a professionally fitted solar kit, as this can feed back into the grid and earn you money. However you have to consider when going DIY the feed in tariff does not apply as you will not be MCS Certified (Migrogeneration Certification Scheme). Once you have measured the most southerly facing roof for its dimensions, and worked out just how many kwh's you will use a day, you need to select your solar power.


As we are looking to size up a reasonable system to allow you to save money, work out what energy you need to store (remembering to allow a margin of error). We have found energy usage plugs to be very usefull as well as the british gas energy meter provided as part of our tariff. You need to get enough batteries to store the amp/hours to last your requirements - we always reccomend to overspec your batteries by around 25-50% to allow room to expand.

Charge Controllers

You have just spent a lot of money on your batteries, now you need a backup policy to make sure your system doesnt do anything lethal. Whilst you can potentially do without a charge controller, what it will do is allow the power to flow back into the solar panel when its dark, wasting your stored power and deep discharging the battery - lethal to any battery! The other thing they do is to prevent overcharging of a battery - another lethal condition!


We assume you are going to be looking into geting the 12v stored in your batteries into useable 240v for all your apps - for this an inverter is a key piece of equipment and will convert your stored power into useable power.
