At this point, it’s only a probably considering going solar and still doing loads of research. Here is a quick guide on the 5 things you should know before Installing solar panels.

Is your house suitable for solar?

When doing solar panels research, the very first thing you will need to know is your house suitable for solar? Here is a list of pointers on what to look for when checking the home is well-suited for solar:

Minimal shading: Solar panels doesn’t work great in the shade. It works best with direct sunlight so the more direct sunlight, the better. If the home is sitting in the shadow of a sky-scraper was built next door to a colosseum, solar panels are unable to be installed.

Your power bill: Do be aware that solar doesn’t work out great all the time. To make the most out of the solar panels, it best for the solar panels to have a power bill of at least £300 per quarter and also to use at least half of your energy during sunlight hours. This is nothing more than a suggestion as in general, the higher your power bill is, the more you will get out of solar panels.

Roof direction: Now this isn’t critical, but is important. To get the most out of installing solar panels, you should have a large North-facing roof or also East-West can also work well. Especially for systems where the inverter is over-loaded.

How Much Will Solar Save You?

It’s a tough one to answer accurately. This all depend on a bunch of things. Here is an approximately basic formula for calculating how much solar will save you:

The electricity rate (£/kWh) x your solar system size x 1,168


The electricity rate (£/kWh) is the rate that you pay for power (what is shown on your power bill).  The solar system size is the size of the solar system you might get (in Kilo-Watts or kW)

The number 1,168 comes from an educated guesstimate of solar production. This number varies depending where you live.

Here is an example:

If you pay 28c/kWh for power and you might get a 5kW solar system, then you will save around:

0.28 x 5 x 1,168 = £1,635.20 per year

Which Panels / Inverter Should You Buy?

There are lots of different solar panels and inverter brands to choose from. Here are some useful rules to follow when choosing a solar panel or inverter:

Solar panels:

  • Choose Logical Heating & plumbing solutions as we been around a long time.
  • Don’t worry where the panel came from, most come from China.
  • Steer clear of panels which try to disguise as being European or having some special properties.
  • Don’t pay top pound, so always get a few quotes and choose a reasonable price and a good product.


  • If the house will be your home for a long time into the future, then do pay top pound and get a great product as it would be a worthwhile investment.
  • If on the other hand you’re buying for a rental property or don’t plan on staying long, then it’s a good idea to get a cheap panel with good warranties.

What Price Should You Pay?

By doing some research, you should have a rough general idea on the solar power systems prices. But beware, there are some very high and very low prices to be avoided. When making a decision, a mid-range price is a good choice. As paying too little and you risk a dodgy product and no after-sales service. But paying too much and you’ll end up waiting 10 years just to recoup your cost. As a general guide, a good 5kW solar power system will approximately cost between £6,000 and £8,000 in today’s market (Mid 2015-16). Pay any less than £5,000 and the risks start becoming too great.
