If you’re finally taking the plunge and going solar then you might have found yourself overwhelmed with trying to decide which supplier and installer to go with. Forget all the sales pitches and focus on these five most important factors – you won’t go too far wrong.

Is the panel Tier 1?

There are so many solar panel manufacturers out there nowadays, but not all of them are equal. Bloomberg has a rankings system for solar panel manufacturers based on the company’s stability and bankability. If your chosen manufacturer is a Tier 1 company then you can be more confident of it producing good-quality panels and still being around to honour the warranty if something does go wrong.

Have a realistic expectation of price

If you want great quality then you’ll have to pay for it and this is true both for the products and the installation. Beware of too-good-to-be-true offers and quotes as it may mean that you’re getting sub-standard goods and workmanship. Low prices can also be so because the installer doesn’t offer the same services and aftercare as others, so look through your contract and quotes very carefully before committing. You also need to be on the look out for hidden charges that come right at the end and sting you.

What’s in the package?

Package deals are great for saving money, but you need to know exactly what your package entails. There could be lower-quality panels, or a cheap inverter, cheap parts or shoddy mounting. All the components should be of the same standard if you’re to get the best out of your system.

What’s the warranty like?

Look for a warranty of 10+ years because if the manufacturer expects it to last at least that long then it’ll probably pay for itself and then some. You also need to look at the warranty on the inverter as it’s the weakest link in the chain – aim for five to 10 years.

How much will you save on electricity?

It’s last in the list but is probably the most important thing to look at. The point of installing solar is to produce your own electricity, after all. You need to find out how much of your electricity demand will be supplied by your PV system and balance this against how much you’ll be spending on it. Our Solar Experts can advise you.
