PV solar panels and battery storage for a sun-powered household day and night

PV solar panels and battery storage allow people to benefit from the sunshine during the nighttime. A game-changer for photovoltaic adoption.


In a nutshell.

Today's battery storage systems is a smart monitoring, management and storage product that puts your solar panels excess power to intelligent use.

75% of a typical household's energy costs are in the evening.

Using the sunshine at night is smugly satisfying.


The science bit.

A lithium-ion battery called the cathode and manufactured with a blend of nickel, manganese and cobalt oxide (NMC).


Specifications:

3-10 kWh output.
750-volt maximum DC input voltage.


It's good to know:

  • Li-ion batteries are well-proven in Chinese taxis, because they do over 100,000 miles and still, have 80% charging abilities.
  • Lifespans and warranties, consisting of decades, comes as standard with modern PV-tech.
  • Tailored systems to suit various budgets.

We love solar panels.

"PV with battery storage was the first game-changer; electric vehicle charging comes a close second."


A different perspective.

Electricity generated on-site has always been the cleanest form of energy and now it's cheapest over the battery's lifespan.

Battery storage enables additional financial benefits from your PV solar panels to achieve a more substantial chunk of self-sufficiency.

Included is a monitor such as the SolarEdge that enables tracking over a day, a week or a year.

There's nothing more satisfying than powering your life, even when you're out all day? Battery storage means storing power to use with your evening and nighttime activities.

Additionally, hot water could be heated too, making your evening bath much more satisfying!

Ultimately, a solution to bring down the cost of living in the 21st-century.

Exciting times ahead.



Questions about PV and battery storage

Is it easy to install?

Battery storage installations come with minimum fuss. DIY installations aren't possible because a Part P electrical qualification is required legally.


What savings can I expect?

A typical house using the national average of 3800 kWh per year and solar PV system generating 3500 kWh per year.

Price of electricity per kWh is 0.12 pence.

The Energy Saving Trust quotes an average saving of 125.00 per year for a typical home; they also quote 0.145 pence per kWh.

125.00 divided by 0.145 = 862 kWh used in the home from the generated solar PV system or a saving of 23% of the 3,800 kWh.

If you use 3,800 kWh per year, you use on average 10.41 kWh per day, so it's only possible to save 10.41 kWh per day.

3 KW solar PV generating on south facing roof 3000 kWh per year.

The unit price of electric per kW, 0.13 pence.

Ordinary PV savings without Battery storage according to the Energy saving trust (EST) is 125.00.

The EST quote 0.145 price per kW so 125 divided by 0.145 is 862 kWh per year.

Battery Storage savings over 300 days @ 5KW (size of battery bank) 1500 kWh @ 0.13p =195.00.

Export payment if available 3000 kWh @ 4.3 p =129.00.

Export payments 3000/2 x 4.86p =72.90.

The total savings for year 1 =125.00 +195.00 +129.00 +72.90 = 521.00 GBP.

(Figures exclude savings from PV-heating converters at approx 200 GBP per year).


How does the battery work?

Lithium ions interspersed throughout many layers, so when the battery gets charged by the sun, the resulting electron current drives the lithium ions out of the cathode and into another layer, called the anode that's made up of stacks of graphite.


How many hours does battery storage give?

Several, but depends on how many appliances are used.

A 10 kWh sized system will give you ten kilowatts over an hour. A hair dryer takes about 1 kW to run, while a washing machine uses several kW to run, but generally, a battery store can power an average household for several hours in the evening.


How long do the batteries last?

Typically, 3000-4000 recharging cycles from a full drain to full charge. The system is designed to switch between devices on demand and seamlessly automatically.


Can I still use Economy 7?

Yes. Ensure you make the installation team are aware that you have Economy 7, so they can structure the install to draw from the grid rather than the battery after 11 pm.


What about a warranty?

All PV solar installations come with a manufacturer and installation warranty of ten years.
