Which energy company is the most helpful about the feed-in tariff

Choosing your feed-in tariff supplier is important. Their efficiency, or lack of it, will affect how quickly and accurately you get paid for the electricity you generate, and you don't have to use the same supplier as you use to buy electricity. A recent blog outlined the questions you sh…

Micro inverters vs string inverters - which works best?

The yield and efficiency of solar PV panels is a constant topic of debate. Talk of kWp and kWh as well as percentage efficiencies of solar PV modules rings out at energy clubs across the land. This is just the headline information though. Just as an obsession with a car's top speed or the…

Fast track review of feed-in tariff rates for solar PV is a blow for community solar schemes

Fast track review of feed-in tariff rates for solar PV is a blow for community solar schemes

Households are the only winners in the Government's fast-track review of feed-in tariffs for solar PV (for generating electricity). Rates for installations of 50kWp or less will not change (and on 1 April they will rise by 4.8% in line with the Retail Price Index). In stark contrast, the rates f…

Shading has more impact on solar PV than orientation or pitch

Shading has more impact on solar PV than orientation or pitch

Many of our clients ask about the orientation and pitch of solar panels - it appears that this has been well publicised. However, the effects of orientation and pitch are less than most people think. Moving the orientation from south to south-west, for example, reduces efficiency by less than 5% as …

Solar PVT: can solar PV and solar thermal panels be successfully combined?

Most of us are now aware of solar panels that heat water and those that produce electricity. But could we install a panel to do both? Solar PVT (PV and thermal) is a concept designed to create electricity and use the waste heat (solar PV panels are only about 15% efficient and the rest of the…

How much are your solar panels generating?

How much are your solar panels generating?

Watching the kWhs clock up as the sun shines is one of the great pleasures of solar PV panels. But which meter do you watch? I watch the total generating meter, and am ashamed to say that I haven't yet worked out what all the different buttons on the inverter do. But that's all about to c…

What to expect from your PV panels throughout the year

What to expect from your PV panels throughout the year

We're often asked how much electricity you should expect to generate from a solar PV system, and how much it will vary through the year. I'm going to use my 2.1kWp system as an example to give you an idea of what you might expect. Our system is mounted on the garage roof. It's a steep (45 degree)…

Why using a solar quote site may cost you more than going direct

Why using a solar quote site may cost you more than going direct

Put solar energy into a search engine and you can almost guarantee that some of the results you get will be solar quote sites. If they aren't in the top 10, they will be in the ads at the side and top of the page. But did you know that you will almost certainly end up paying more for your solar pane…

Solar industry starts and ends year with uncertainty

It feels as if the solar industry has been on a real rollercoaster during 2010. This was the year where we were finally meant to have an end to the stop start funding of the various grant schemes that have supported the sector in the past and move into the 21st (solar) century with the launch of a f…

Solar PV farms - are they good for the UK?

Whether large scale solar PV farms are relevant for the long term in the UK was one the first questions asked at RegenSW's Question Time debate this week. No, was the short answer from Sarah Rhodes, the head of land-based renewables at DECC, although she put it less baldly than that. Due to the …

Feed-in tariff is proving a big success

The government's feed-in tariff scheme has already got thousands of people generating their own electricity. When it launched the feed-in tariff scheme in April it was one of a range of policies aimed at inducing people to improve the energy efficiency of their homes. Now, just five months later, an…
