How Many Solar Panels And Batteries Do I Need?

Are you presently considering adding a solar system to your home? With several homeowners in the UK using solar now, many more are realizing the numerous benefits they stand to derive by getting one. Therefore, if you’re thinking about adding the system to your home but do not know where to start, you’ve come to the right place.

Here, we’ll help you calculate the number of solar panels and batteries you’ll need to power your home. Starting from the panels, you can begin by taken into account everything that makes use of power in your home to get a good idea of how many you’ll need.

• Firstly, you’ll have to determine the number of watts you use. 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.

• Secondly, you have to determine the peak sunlight hours - having in mind that the solar panels only work when under direct sunlight. Once determined, you can then multiply the figure in hours by your home’s hourly energy usage and divide by your selected solar panel’s wattage.

Generally for a 1500 square foot house, you might need around 15 to 18 solar panels to cover the house’s electricity.

Meanwhile for batteries, there are also some factors to be considered to determine the number of batteries you’ll need for your house. These factors include your home’s power or electricity usage, the period of time in which the battery will be used as well as the battery’ specifications. Once done, you’ll be able to calculate the number of batteries required by your home.

Unlike in houses built in the 1970s where a good majority of the houses will not need to be rewired, for houses built in the 1960s you’d probably need to rewire the entire house unless the wiring is the modern PVCu coated type. Generally, the homes built especially in the 1960s and 1970s brought about enormous changes. This is because over the years our way of living began to change and as a result, our need for electricity became even greater. In response to this, the electrical systems we incorporate needed to change in order to match the new set standards.

In the 1960s, the amperage normally used was increased to 100, which enables home and property owners to power their dishwasher, microwave as well as refrigerator all on one circuit. However, while this may be a remarkable improvement for our grand parents, this is just enough to cater for our modern day appliances. In recent times, new homes are constructed using a wide range of dedicated circuits due to the fact that each of our appliances makes use of much more electricity to function. Consequently because the 100 amp panels of the 1960s possessed restricted space for breakers, home and property owners who still had the units in their homes will inevitably require a sub panel or a new panel entirely - meaning a total rewiring of their property.

Furthermore in the 1960s, builders turned to aluminium from the previously used copper as it was a great conductor and also happens to be relatively cheap. However, after a couple of years a host of electrical fires cropped up in houses that are wired using aluminium. It was later discovered that when the switch to aluminium was made, the light switches or receptacles which were originally made for the previously used copper was overlooked. It was learned that there’s a corrosive chemical reaction that arises as a result of the two dissimilar metals when connected. Hence, the more reason why aluminium wired houses in the 1960s needs to be rewired.

Registered Electricians will certainly work in uniformity with the UK nationwide criterion, BS 7671 - Demands for Electrical Installations. They will certainly provide a safety and security certification for their electric work to verify that the setup has actually been created, built, evaluated and evaluated, based on the standard.

You should guarantee that your selected Electrical installer is signed up with one of the adhering to companies:

• BRE Certification Ltd
• British Standards Institution.
• ELECSA Ltd
• NAPIT Registration Ltd
• NICEIC Group Ltd
• SELECT (Scotland)
• STROMA

An electrical safety inspection is basically the act of carrying out a thorough assessment of all electrical systems within a property, be it residential, commercial or industrial premises. The main goal of conducting this survey is to see to the fact that all the electrical systems and installations forming part of a property are correctly fitted, well maintained and ultimately, safe. This is required to be carried out by an electrician who’s an approved contractor and accredited by ECA, NICEIC or STROMA. To get contractors who can carry out the electrical safety inspection and meet with the government criteria, you simply have to search on the Electrical Component Person database. They’ll assess the current condition of the electrical systems and evaluate if they are working efficiently while also paying special attention to any defects or faults.

Generally, the best way to get an electrical safety certificate ( an EICR) is to shop around. In the event whereby you need the inspector to examine a part of your property you’d have to raise his/her awareness to this. This will be referred to as an “agreed limitation in the report.

Failure to comply with electrical safety regulations bring about serious penalties for such landlords. Upon the introduction of the new regulations in June 2020, local authorities can fine the electrical safety regulations-breaching landlords up to £30,000. Asides this fact, it’s also in your interest to keep your property as well as its appliances in a good condition at all times. If everyone including your tenants feel safe and your property is in great shape, everyone is happy!

The cost of an Electrical Certificate varies depending on the size of your home as well as the number of electrical installations and appliances that needs to be checked. The price can start anywhere from £120 and above.

Most people want to connect solar panels to a battery when they’re not at home all day to use the electricity they generate, or generate more than they consume over a day. Solar batteries are a great way to maximise the savings on your energy bills since you can use every unit of electricity you generate.

If you want to connect your solar panels to a battery, the best – and safest – way is to ask an MCS-registered company to do it for you. They’ve had lots of training and hold qualifications in handling electricity and installing solar batteries, so they will be able to recommend the best battery for your solar panels and for the among of electricity you use. Some of the brands they might recommend include Tesla, SolarEdge and SolaX, but there are many more to choose from. If you want to send electricity to the grid from your battery to receive Smart Export Guarantee (SEG) payments, it’s also worth leaving installation up to a registered installer. This is because you might not be eligible for payments if your battery wasn’t installed by an MCS-registered company.

However, if you do want to have a go at connecting your solar panels to a battery, it’s worth finding out whether your system is ‘storage ready’. Most relatively new systems will be, since batteries are becoming more commonplace. If your solar panels are storage ready, they will have an inverter that can easily have a battery added to it. If this is the case, then you should be able to buy the solar battery you want and follow the manufacturer's instructions to install it.

But it’s worth remembering that electricity is extremely dangerous when handled improperly. If you don’t get the solar battery connected properly and something goes wrong, it could cause a fire or you could electrocute yourself. If a fire breaks out due to your battery, it’s unlikely that your home insurance company would pay out since you connected the battery yourself. That’s why it’s always worth speaking to a registered installer to install a solar battery storage system for you.

The importance of selecting the right size battery for your home simply cannot be overemphasized. A lot of home and property owners are facing this challenge and understandably so. Selecting the right battery size for your needs depend on a number of factors which includes your motive for adding a battery, your electricity usage, your budget as well as your panel array size, be it new or existing. In this post, we’re going to take you through some of these factors to help you determine the right battery size for your home or property. Let’s take a look!

• Your motive for getting a battery. While most people purchase a battery to wipe out their need to purchase electricity from the grid with the hope of making some savings, others add a battery so as to enjoy backup power. There are also some who just needs it to power their home with solar energy. It’ll not be economical to size a battery to effectively take you off the grid, but if your motive is to make savings, then you’ll should expect to purchase some electricity from the grid during the year.
• Electricity usage. The average household uses about 16kWh of electricity on a daily basis. During the daylight hours, most of these household will use a third of their electricity when the solar panels are still generating electricity, while the remaining two third are purchased from the grid. In other words, you’ll require a minimum of 10kWh battery capacity if you were to use a battery to power the electricity you purchase from the grid.

For a typical British household, you’ll most likely need a 5kWh solar power system which normally generates about 17 to 21 kWh on a daily basis depending on your location in the UK.

The OLEV Grant, also known as Electric Vehicle Homecharge Scheme (EVHS) can reduce the cost of your home charger by up to £350. If you're eligible, you'll be able to claim it when you buy an EV charger.

With each year that passes, the amount of electric cars on the road keeps rising and with them comes a necessity to develop new infrastructures and also accessories like charging cables as well as connectors for easy sustainability. This concept is still pretty much new to the general public as most people still use vehicles that are fuelled by petrol and diesel. There are also some differences in design which asides from the lack of an engine underneath the vehicle’s bonnet, the way in which an electric car is filled up largely varies petrol or diesel powered vehicles. There’s a lot that people will have to learn about electric cars and even more so when it comes to their everyday use. One of the most common questions a lot of individuals ask about electric cars is whether all electrical vehicle chargers are the same. If you’re also looking for an answer to this question, then you’ve come to right place!

If you’re interested in getting an electric car, charging your vehicle at home may not generate any major concern but what about making use of the public charging system? This is when it gets a bit confusing because if you’ve never had to do it before you may worried about making use of the wrong charger on your car. So the question is, does every electric vehicles have the same plug? The answer is simple - there are different plugs and cables for varying electric vehicle brand as well as points of use. In general, you’d have to choose most suitable charging level for your electric vehicle.
