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

Where:

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.

Inverter:

  • 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.
