#SolarUpdate A quickie before bed... oooer 🤔

3 weeks into May... here's the data

10.5kwh of electric imported (£15.82 inc standing order fees)

264.3kwh of electric exported (£36.95 earned)

£9.53 of gas used (inc standing charges)

Current bill +£11.60 credit

529kwh generated in total (May 2024 was 485kwh, May 2023 was 668kwh)

170kwh used directly,
118kwh sent to the battery
246kwh sent back to the grid

Daily avg 25.2kwh

It's been an exceptional month so far, and whilst rain is forecast for the end of the week, it's scattered showers rather than dark clouds and heavy rain. So solar forecast is still looking reasonable for the next week.

Instead of it predicting 207kwh of generation for the last 7 days, it's predicting 130kwh, with an avg of a 50-60% chance of rain each day from Saturday onwards. Which is still a daily avg of 18.5kwh and would only bring the daily total to the 28th down to 23.5kwh a day.

It would also mean (if it's accurate) that we'd equal, if not beat the previous record of total generation in a single month... Which was also May 2023 (668kwh).

Only 10 days left in the month... will we break records or won't we... Tune in and find out.

#SolarUpdate 2 weeks into May and here's the data.

347kwh of electricity generated
158kwh of electric exported back to the grid
8.5kwh of electric imported

So after 14 days, we've spent about £11.30 on electric (inc standing charges)

We've earned £23.70 from exporting.

We've also spent about £6.30 on gas (inc standing charges)

So our bill for the first 2 weeks of May is about £17.60 and we've earned about £23.70.

Which means so far this month, we are about £6 in profit.

We still paid the £100 direct debit the other day, so the credit on the account is currently up by £106.

The best day so far this month was 27.71kwh of generation, we've had an average of 24.7kwh of electric per day.

The lowest day was 12kwh and that's the only day so far this month below 22kwh.

The best ever day we've had was may 2023, when we generated 29.7kwh.

Forecast for the next 7 days is more of the same... 192kwh of solar generation is being predicted for the next 7 days.

At this rate, we'll surpass last years 555kwh for May with 9 days left in the month, and current predictions for the month are over 700kwh.

We use around the 390-450kwh mark each month... lower over warmer months as we use sunshine to dry clothes rather than the tumble dryer. So if we hit 700kwh generation, at least 300+ of that will be exported for around £45+

Construction starts in Switzerland for the world's largest battery storage facility.

The world's largest battery storage facility is being built in a new technology center in Laufenburg (TZL) in the Swiss canton of Aargau.

The redox flow battery, also known as a liquid battery or wet cell, will have a total capacity of more than 1.6 GWh and an output of over 800 MW.

Construction of the TZL began at the start of this week.

#SolarUpdate As we move into the more sunny and productive part of the year. I do more regular updates on the system.

So after 1 week of May, here's a few stats.

179kwh of solar generation
87kwh of solar export.
3.7kwh of import

Avg daily generation 25.5kwh
Avg daily use in the home 13kwh
Avg daily export 12.4kwh

When you factor in the daily charges for electric, the current energy bill for electric is about £6. If you add on the gas charges since we turned of the heating at the end of April, it's a total of £9

The earnings from the export £13

So after the first week of May, we are roughly £4 in profit for the month.

Researchers in Alberta are developing saltwater batteries.
"“With current options for energy storage like lithium batteries being too expensive for long-duration storage, Aqua-Cell Energy is everything lithium is not,” he says. “Our flow battery pumps saltwater through a battery stack where electricity is applied to store energy in the saltwater.”

He shares that when this process is run in reverse, it generates usable electricity.

“Our technology is the world’s most environmentally friendly #battery storage option … and using low-cost saltwater as the electrolyte allows for affordable long duration energy storage of upwards of 12 hours.” "
