National solar power within 10 years (national grid supply)?

Green power being cheaper is a lie, at least for the next 15 years, its the EU and worlds dash for Gas as a fast acting 'back up' that is the reason for high prices, The Government plan for 2030 is for 40GW of Wind and small module nuclear, 5GW of HYDROGEN,  interconnectors and then one day fusion power.  Little mention of more large scale Solar.

page 26 for estimated power bills in 2030 still being 1200 a year!

Yes and no. Green electricity may well be cheaper at times; however, as reported elsewhere, the price of the electricity that we purchase is set on the basis of the cost of the gas used to produce it. Given that in recent days, over 55% of our electricity has been produced from gas and coal, then this is unlikely to change anytime soon.

The main point being wind and solar will not crash the price of power in the next 10 years, making home solar worth it, whether its 7 years at current prices or back to 1200 a year and takes 10 years.

But then maybe in 7 years time we will all have a home battery and use cheap night wind power.

It is worth reading this article which points out that producing green energy is one challenge: the other is getting it to consumers on a National Grid that is configured for a bygone era:

For a start you're being massively over quoted for your installation. A 5kWp solar PV system with an 8.2kWh Givenergy battery with hybrid inverter should cost ~ £7k. Someone on Facebook reported paying £6,500 for this system last summer. You need to get some other quotes and I strongly recommend joining the solar and battery Facebook group.

Now, onto the future price of electricity: none of us know what prices will do. All you're doing by investing in this kind of technology is mitigating against the possibility of future price rises while ensuring your own usage is as sustainable as possible. It's a bit like fixing your mortgage for 10 years. It's a gamble but you guarantee what you're paying rather than being exposed to the volatility of the market.

Interestingly the cheapest year on that chart is 2025, and the only year cheaper than 2030 is 2017.

He was so close to saying it will be 'too cheap to meter'

I had to go refresh my memory on Sir David MacKay's Numbers for wind, 'Energy Without hot air' p73

http://www.inference.org.uk/sustainable/book/tex/sewtha.pdf

"The UK government announced on 10th December 2007 that it would permit the creation of 33 GW of offshore wind capacity (which would de-liver on average 10 GW to the UK, or 4.4 kWh per day per person), a plan branded “pie in the sky” by some in the wind industry. Let’s run with a round figure of 4 kWh per day per person. This is one quarter of shallow 16 kWh per day per person. To obtain this average power requires roughly 10 000 “3 MW” wind turbines like those in figure 10.1. (They have a capacity of “3 MW” but on average they deliver 1 MW. I pop quotes round “3 MW” to indicate that this is a capacity, a peak power. "

Thanx for the above "Petrix"

I've got a profile on FB and will click the button asap. Also, shocked at how OTT my quotes are (or, does my 570Kw per month not put me up a cost level from the 5kw max requirements (cabling, servicing, battery?). Also, live on the coast in Lancashire so is not  the salt and sand due to high winds going to add to my guarantee costs?

Thanx for all responses. I'm definitely learning a great deal here.

Not sure if my daughter might not need medical help with the massive grin on her face!

Again, apologies for my naivety.

You cannot get 570kWh every month from any array that you could put on the average domestic roof. My 7kWp array has monthly target outputs ranging from 108kWh in December to 827kWh in June. I have also had daily outputs as low as 300Wh on a dank December day. I have a 13.5kWh battery and  I still end up importing 1000kWhs/year from the Grid and exporting 2000kWh/year to the Grid.

Your daughter has the advantage of being able to use the solar energy that is produced to support her non home activities.

You will probably want bird blockers as part of the install then to keep nests from being made under them.
