Why buyers should take care when investing in renewable heat

Let me set my stall out: I'm a fan of renewable heat technologies if they are installed well in suitable buildings. I'm also delighted that details of the domestic renewable heat incentive scheme has finally been announced, and that the rates are higher than expected.  But, and g…

Review of Elios4you energy management system

I'm often surprised about how much electricity my solar panels generate, even on a cloudy day. Despite it being June, I'm writing this wearing a thick fleece to keep warm, and looking out at around 90% cloud cover, yet my Elios4you device shows me that our 2kWp solar PV array has been ste…

What happens to the feed-in tariff if I switch energy suppliers?

Q: I'd like to look for a different energy provider (my current one, nPower isn't paying its tax!). However, I don't want to lose my feed-in tariff (FIT) payments. Can I reapply for them with my new supplier and is it a complicated procedure? Or will my old supplier keep paying the FI…

How important is the efficiency of solar panel?

A more efficient solar panel is a better one, right?  Well arguably, but it doesn’t necessarily make it the most appropriate choice for use in any given situation. That's why I'm starting my series on what is the ‘best’ solar panel by looking at the sometimes c…

What is the feed-in tariff rate with inflation rise?

Q: My PV installation is now 2.5 years old. The feed-in tariff (FIT) is supposed to rise with inflation each year but wherever I search on the web I can only seem to find the rates for new installations. I am registered with Scottish and Southern who no longer provide a breakdown of payments and …

Will solar PV power my underfloor heating?

Q: We are having a 4kW solar pv system fitted. We are also considering electrical underfloor heating. After reading some very interesting pages on your site I am beginning to wonder if electrical underfloor heating is the best option as this will mainly run when it is dark? Is my thinking flawed …

Who deals with claims on an inverter warranty?

Q:I have a quote for the installation of solar panels. The quote says that the inverter is guaranteed for 10 years and that the guarantee is directly with the manufacturer; ie the installer does not wish to be involved in any guarantee claims. Is this normal? Is this contrary to the Sale of Goods…

How voltage affects solar PV

How voltage affects solar PV

As most people will know mains voltage in the UK is  - nominally - 230V (it was 240V until we compromised with the European 220V supply).  But why does it change in both time and place even within mainland Britain? The answer to both stems from Ohm’s law. The voltage drop in t…

Building Control regulations for solar installations in Northern Ireland

Building Regulations is one of the most common things we’re asked about during initial enquiry and survey stage. This isn’t the sexiest of subjects when discussing solar PV, but it is important to understand the rules from the outset. In most cases, and without exception if solar is t…

Which solar panels are best?

Choosing the best solar panel is a bit like choosing the best sandwich for your lunch. What’s better for you – a BLT or a cheese and pickle sandwich? Well, the cheese sandwich wins in terms of lower calories and lower fat, but the BLT contains more protein and more vitamins and nutrie…

Is my roof strong enough to take solar PV?

Q: I live in an old stone cottage (c 1830) with roof rafters that I'm sure wouldn't pass current building regs for strength, even though they're not the original ones. The walls seem sound enough though. Would it be possible to put up a solar pv array that was supported on the 2 end w…

Five reasons why now is a really good time to install solar PV

If you want to generate your own electricity there's not likely to be a better time than now to install solar PV panels. Global oversupply of solar panels has led to tumbling prices - but experts predict that this may not last. The feed-in tariff - the government's incentive for the t…
