How Do Solar Panels And Batteries Work Together?

With solar panel system rapidly becoming an ubiquitous phenomenon within the modern society, several homeowners in the UK are just coming to terms with the numerous benefits offered by the system. The solar power’s popularity has even led to the rise of another renewable technology - solar batteries able to store excess solar power that can be used later. Now several companies such as Tesla are now building solar batteries that can be fitted alongside solar panels for your building. So how exactly do solar panels and batteries work together? Let’s have a look!

Solar panels make use of the sun light to generate electricity and as a result, they can’t function when sunlight is absent - giving a big issue of how to power your house when it’s dark. In the event whereby this occurs, you’re afforded two options which is either to contact energy providers to buy electricity or purchase a battery storage system.

So what’s the function of the battery storage system? Basically when your solar panel provides electricity which is not needed right away, a solar battery will work to convert the DC electricity into AC energy which is going to be stored for later use (when you actually need it). in other words, your solar panels charge the batteries when you do not require the energy they’re generating right away.

As a result, when it’s dark and the solar panels are no longer functioning, your system will tap into the energy that’s already been stored by your battery for later use. This way, you can be totally independent of the National Grid, which implies more savings on your electricity bills.

Can You Replace Storage Heaters With Electric Radiators?

The short answer to this question is yes. If your outdated storage heater is not heating your home the way it should, you’ll find a better replacement in electric radiators.

Being more modern and efficient, electric radiators offer a wide range of benefits which storage heaters can only dream of. Let’s have a look.

• Unlike storage heaters, electric radiators do not need to be charged up the night before which makes it totally controllable as you do not have to guess what your heating needs will turn out to be the next day.

• The above benefit leads to an even better one as the controllability quality of electric radiators makes them a lot more efficient than storage heaters. Electric radiators usually comes with programmable timers and thermostats which allows you to set various heating schedules for each of your rooms, meaning you’re only heating when and where its needed.

• Unlike some storage heaters, electric radiators do not cause wall blackening and also happen to more elegant and stylish.

• Electric radiators are not tough on allergies like storage heaters as they do not depend mainly on convection to heat

• Electric radiators also have an easy installation process with all you need to do to switch from storage heater to one being the removal of the former and inserting the radiators into the sockets.

However, if you want to make a switch to electric radiators, there’s the need to change to a standard electricity tariff from your economy tariff. And while the standard electricity tariff rates may be more expensive than the night time rate provided by Economy 7, the standard tariff rates are a bit cheaper than the daytime Economy rate. You’ll also get to use much less of electricity while also saving money on your heating bills and more.

Most domestic solar thermal panels do not need planning permission and are covered by permitted development rights. There are restrictions on the size and location of these systems. If you live in a conservation area or listed building, or want to install a very large solar thermal system, check with your local authority to see if you will need planning permission.

There are a few reasons you may need a new fuse box. This would include: The box being old or out-of-date, Insufficient or no RCD protection, Holes or gaps in the casing, Not compliant with legal specifications. An electrical survey will ascertain if one is needed.

The cost to charge an electric car in the UK varies between home, work and public charging.

For a typical electric car with a 60kWh battery and ~200 mile range:

• Charging at home: Costs about £9.20 for a full charge. *
• Charging at work: Many employers will install workplace charging points and typically offer free access throughout the day.
• Charging at public locations: Public chargepoints at supermarkets or car parks are often free to use for the duration of your stay.
• Rapid charging: Rapid charging points are normally found at motorway service stations and typically cost £6.50 for a 30 min, ~100 mile charge.

Charging an electric car at home costs about £9.20 for a full charge* and is the most convenient and cost-effective way to keep your car fully charged. Most drivers will charge their electric car overnight, waking up to a full battery every morning.

Average domestic electricity rate in the whole of the UK is about 17p per kWh.

Fully charging a 60kWh electric car will cost between £9.00 and £9.90 (depending on where you live) and give you about 200 miles of range.

* Costs calculated at 17p/kWh based on usable battery is ~54kWh (90%).

If you are thinking of buying an electric vehicle, then one of the first things you’d have to put into consideration is charging. When it comes to charging of your electric vehicle, doing it at home is one of the most convenient things that comes with it. Not only do you get to avoid the fuel stations, but you’d also get to drive a car in a much cheaper way. Fitting an EV charger or wallbox at your residential space gives you the option to add miles to your battery in a lot faster manner than making use of a three pin plug. In fact, there are also some chargers that offers a lot more than just being a fast way to charge your vehicle.

So which home ev charger should you use? There are a wide range of options available in the market today, however you can get the perfect match for your vehicle by answering these few questions:

• Can you park two cars side by side? If yes, then a tethered charger might just be your most suitable option. A tethered cable is one that’s always connected to your home’s charger. One of the major benefits of using this is that you can get home and plug the charger straight it without having to fetch the cable or carry it around.
• Is size and design crucial? If yes, then you can consider wallbox chargers or untethered wallboxes which are smaller in size and minimalist in design.
• What if your WiFi isn’t accessible? If your WiFi signal is poor in the spot where the charger is to installed but your mobile phone signal is good, then Ohme is a good option to consider.

How Many Solar Panels And Batteries To Power A House?

Do you wish to know the number of solar panels and batteries sufficient for a house? Well, this is a frequently asked question in the solar world which would be very difficult to provide an accurate answer. This is basically down to the fact that all homes are unique with different sizes as well as amount of daily energy requirements. As a result, the number of solar panels and batteries needed would be unique to the house in question. However, we’ll consider the varying influencing factors that will go a long way to help calculate the number of panels and batteries needed to power a house.

First and foremost, let’s take a look at the solar panels. You’d have to start here by putting into consideration all household appliances that makes use of power in the house to get a good idea of how many that’ll be needed.

• How Many Watts Is Being Used In The House On A Daily Basis?

To determine this, simply go through your utility bill for kilowatt-hours (kWh). This varies amongst homes and being able to identify your daily average energy usage will assist you in getting your solar needs.

• What Is The Number Of The Peak Sunlight Hours At The House’s Location?

Having in mind that the solar panels only work when under direct sunlight, the first step to determine the peak sunlight hours. Once determined, you can then multiply the figure in hours by the house’s hourly energy usage and divide by the solar panel’s wattage.

Overall for a 1500 square foot house, the number of solar panels that’ll be required should fall around 15 to 18.

Meanwhile for batteries, there are also some factors to be considered to determine the number of batteries that is required to power a house. These factors include the house’s power or electricity usage, the period of time in which the battery will be used as well as the battery’ specifications.

Obviously the performance of a solar thermal system will vary depending on the location of the home, the insulation of the property, and your own hot water requirements. Solar thermal panels are capable of providing all of your hot water requirements from April to September. They will still make a contribution to your hot water needs for the rest of the year, but in general you will need a backup system to further heat the water in the colder months.
