Sunny Feb 2019 Beats Solar Records

In the UK Feb 2019 was one of the hottest and sunniest February months on record and this has also been reflected in the generation numbers for our solar panels. You can see the comparison here

http://solar-panels-review.321web.co.uk/index.php/yearly-comparison-of-solar-pv

The previous highest electricity generated in Feb was 190kWh so the 226kWh for Feb 2019 was nearly 20% higher than the previous maximum. Unlike 2018 this year was warm and dry with no snow which gave some good daily generation but no records for the daily production, probably because it was too warm. Cold sunny winter days are best for getting the most solar power generated.

Best January Solar Day

This year we've had the best January day for our solar panels with one day production of 10.2kWh of electricity.

As panels age they will degrade over time and reduce by approximately 0.5% per year. Interestingly so far there has been more variation due to weather than from the panels reducing.

FIT Rates April 2019 Onwards

The latest inflation figures have just been published which set the level of the Feed In Tariff rates from April 2019 onwards. The common inflation measure released is the CPI (Consumer Price Inflation) which is 2.2% for December but this isn't the one that is used to calculate FIT payments

The inflation measure used is RPI which is more difficult to find as it's not so commonly used any more. If you go to the ONS website you can see the latest value for RPI for December which is 2.7%

Using the existing FIT rate of 52.75p and applying the RPI of 2.7% gives a new rate of 54.17p
for the Feed in Tariff rate as of April 2019-2020. The level for export will increase to 3.82p

There are various other FIT rates that apply depending on the date that your solar panels were commissioned. They will also increase by 2.7% as the RPI rate for December 2018.

Project Solar - Good Priced Solar Panel Quote Or Rip off Prices?

Lots of people on the Moneysaving Expert forums are reporting quotes from a company called Project Solar that appear to be extortionate. The price of solar panels has come down massively since we got ours installed in 2011. The FIT rate has also dropped since then so it's not all positive news!

Project Solar Good Priced Quote?
Project Solar Good Priced Quote?

Our panels cost £8999 for 14 panels rated at 3kWp but an equivalent now would be under £5000, suggestions are that you're now looking at approx £1000 per 1kWp of generation capacity so approx £3000. Forum members have reported paying £6000 for 5.1kWp of panels installed.

Project Solar appear to work in the same sort of way as doubling glazing companies of old - quote a high price and then drop it a bit to get business. The problem is that dropping a bit still isn't competitive and I'm always very wary of companies that are trying to rip you off with their original quotes.

In addition to the price one tactic that I've found several suppliers use is to suggest that inflation for electricity will be very high over the next 25 years because prices rose significantly over the last couple of years. In reality if prices rose by anything like the amount that some quotes are claiming then we'd be paying 75% of our wages on electricity by 2030!

October 2018 Record breaking Solar Month

October 2018 has been another record breaking month for our solar panels with 274kWh generated, significantly higher than the previous best of 235 kWh back in 2016 and 73kWh more than last year.

It's actually been quite a year of extremes with March and April 2018 coming in well under previous years but May and June and October now being much higher.

2018 Solar Panel Data Updates

I've now added the data for our solar panels for the 9 months up to the end of September 2018. With the very long hot summer we've had some great months

http://solar-panels-review.321web.co.uk/index.php/yearly-comparison-of-solar-pv

May & June 2018 have had the best performance ever by quite a considerable margin. May 2018 was 447kWh when the previous best was 403kWh in 2014. All May solar data here

 June 2018 was 462kWh with previous best of 431 in 2017. The June data for our solar panels is here

Solar Data to June 2018

I've now loaded the first six months of 2018 data to 30 June. Some interesting data that shows the "Beast from the East" cold weather event in March 2018 and how fantastically sunny June and May 2018 were with record solar generation during those months.

In the UK as a whole solar has made a much bigger contribution this year too.
