SMA inverter extended 10-year warranty

It is now coming up to 4-months since I had my solar panel installation, and finally this week after repeatedly chasing-up the installers, my extended SMA 10-year Sunny Boy inverter warranty certificate has arrived. Even towards the end, this was not without complications. The warranty paperwork did arrive 11-days earlier only to be returned because the serial number on the certificate did not match that of the inverter. Something that potentially could prove to be a very worthwhile check before filing away.

With the feed-in tariff agreement documents also recently sorted, this now concludes the original installation of the south, south-east solar panel array. I can now, hopefully look forward to many years of trouble free service.

Solar Panel Tariff Appeal Fails

Anybody who had a solar panel system installed after December 12th 2011 and before the final cut-off date of  March 3rd 2012 can now breath a sigh of relief. The Supreme Court today rejected the appeal from DECC (Department of Energy & Climate Change) to cut subsidies for solar panels on homes installed during this period. This judgment now means that all domestic panel installations completed before 3rd March this year will still get the higher 43.3p feed-in tariff rate for 25 years.

Solar Electric Generation – February Stats – East West Split

Late again, but here are the east-west solar array split’s February generation statistics. These stats are from the 2.64kW system, which employs SunPower 240kW E19 Series solar panels with SolarEdge power optimisers.

I expect that some of the more keener viewers of this site will have spotted that I have not reported on part of January. I was reporting on each month from the installation date. However from this month on to make solar generation statistics a little clearer I have started by reporting by calendar month. This will make comparison against the south, south-east system easier to compare. I will try to add the missing January statistics later.

East-West split solar generation stats for February 2012The electricity generation statistics are for the period from February 1st to 29th. During this second reported month the system harvested just over 91.2 kW of electricity, averaging 3.15 kW per day. The chart also shows the highest day of generation at 6.71 kW.

Electric Generated From Solar Panels – During February

Things truly have now started to improve, the longer days reported on the 19th February made a big difference. I’m already thinking about the prospect of March as the solar harvesting figures begin to look really interesting.

This is the third month’s generation statistics since my Sanyo solar panel array was installed. Within the previous South, South-East solar panel statistics blog on 24th January I reported that my 2kW system had harvested just over 63.5 kW of electricity, averaging 2.05 kW per day.

At the time of the last stats blog I was reporting on each month from the installation date. Today and from from this month on to make solar generation statistics a little clearer I will begin by reporting by calendar month. This will also make comparison against the East-West split system easier to analyse.

Today’s entry shows that during the month of February my solar array yielded 102.74 kWs of electricity from the sun, averaging 3.54 kW per day. That’s a good increase from January. The solar system chart below also shows its best day with 8.94 kWs being generated on the 26th February. The longer sunny days will keep improving these figures for some time to come….

February Solar Generation Statistics - Month Three

Arrival of the feed-in tariff (FIT) agreement

Back on the 18th February I made a determined effort to try and tie up a few loose ends left outstanding from my solar panel installation in November. This was only unresolved paperwork issues but nonetheless very important to clear up.

One of the issue was that of the outstanding Scottish and Southern Electric (SSE) feed-in tariff (FIT) agreement. I left this still outstanding on the 18th which was at that time approaching three months from my solar array fit date. I was expecting a promised call-back from the microgeneration department within five days. Well, the call never materialised and was still waiting over two weeks later.

This week I called the department once more and explained the situation. This was then escalated to a manager and I was called back later the same day to confirm that my contact would be in the post that evening. And sure enough it arrived the very next day – job done.

The agreement came with a covering letter thanking me for appointing Scottish & Southern Electric as the FIT licensee. This is all very similar to that reported before for my fathers solar panel system on 4th February. The document confirms that I have been registered for the FIT scheme and there is also a contract to sign and return.

Also stated within the communication are the submission dates that the meter readings must be taken. It is to be read and submitted to enable quarterly payments for FITs generation and export. These figures can be emailed or phoned through on or around the required dates.
