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.

When it comes to electrical works, safety is always paramount. Although a complete house rewiring service may seem quite expensive, when compared to the safety it provides, you’d realize it’s well worth it. We know all too well that human nature tends to prevail to overlook small electrical issues until it’s too late or probably gets out of hands. When this happens, not only will you have to spend more to get the issue resolved, but it may also lead to some damages to your property. Hence, the need to identify and resolve electrical deficiencies as soon as possible. In this post, we’ve compiled a shortlist of some of the top signs that your house needs rewiring. Let’s take a look!

• Dimming or flickering lights. This is one of the most common signs that your house needs to be rewired. When a light brightens, it means there’s too much voltage and when it dims, it implies it’s receiving too little voltage. You may be tempted to think this is a lighbulb issue, but this type of decline in power is usually as a result of a loose wiring or faulty circuits which should not be ignored.
• Regularly blown fuses. With the steady development in technology as well as electrical appliances within our houses, older style fuses that are not designed to contain this amount of electricity will end up blowing. If your fuse blows on a more regular basis, then there may be a need to upgrade them to more modern circuit breakers.
• Lightbulbs burning out in their sockets. This is usually a sign of bigger issues in your wiring which is often caused by fluctuations in voltage.
• Sparking outlets. These can be perfectly normal, but at times they can also be a clear signal of a potentially dangerous problem which should not be ignored.

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.

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.

If you’re planning to get an electric vehicle, the next thing that naturally comes to mind is getting a good charger with it. As a result, this is one of the most common questions asked when it comes to electric vehicles. We’ve put together this list of some great home ev chargers to help you make the best informed decision possible moving forward. Let’s take a look!

• Charge Point Wi-Fi Enabled Level 2 EV Charger. If what you need is a faster charge for your car due to the high frequency of usage of the electric vehicle, then this charger might just be the best option for you. It’s claimed to charge electric vehicle batteries six times faster than a standard 120 volt home system. What’s more? The mobile application will inform you about the amount of charge your battery has regardless of your location. This feature can be of great benefit especially when you’re trying to determine whether to put in an additional hour at work or heat straight home.
• Juice Box Pro 40 Level 2 EV Charger. This is a level 2 charger which features a web based charging control so as to allow you control the charging parts of your vehicle from anywhere, be it in the comfort of your home or office without having to go to the garage or parking lot.
• Siemens VersiCharge VC30GRYU. This is an easy-to-use plug and play installation that comes with a mounting bracket if you happen to own a NEMA 50 receptacle. It boasts a charging time that’s 4 times faster than level 1 electric vehicle chargers and possess a charge delay feature or 2, 4, 6 or 8 hours.

If you’re looking to install a solar thermal system in your home, this is usually one of the first concerns several homeowners have. Being fully aware that solar water heating systems are usually more expensive than their counterparts - the conventional water heating systems, the question arises whether or not you’ll be able to save some money from your solar water heating system in the long run. In this article, we aim provide an answer to this important question. Let’s take a closer look!

When it comes to solar thermal systems, the money you’ll be able to save in the long run depends on a wide range of factors. These factor includes:

✓ Your system’s performance.

✓ Your geographical location and solar resource

✓ Your household’s hot water demand

✓ Financing and incentive options that are available.

✓ The cost of fuel that’s being used for your alternative or backup water heating system, if you own one.

✓ The cost of conventional fuels such as oil, electricity or natural gas.

There are several benefits, however, that comes with the installation of a solar water heating system. Since the sun is absolutely free, future fuel shortages and price hikes will have little impact on you. Also, on the average if you decide to fit a solar thermal system your water heating bills is expected to drop about 50 percent to 80 percent. What’s more? The economics are even a lot more attractive when you’re just about to build a new home or refinancing. When you include the price of a solar water system in a 30 year mortgage, it’ll normally amount to very low price per month. Therefore, on a monthly basis you’ll be saving more and paying less.

Fuse box prices will vary and a periodic inspection should be carried out first. However, domestic fuse boxes cost an average of £460. A qualified electrician will advise if yours needs to be replaced and it's always a good idea to obtain a number of quotes before committing to this.

Also commonly referred to as a consumer unit in recent times, a fuse box is responsible for controlling and allocating of the electricity in your home. They hold the power any time there’s an overload in one of the circuits which in turn, prevents fire as well as electrical damage. Fuse boxes are often incorporated in homes but consumer units are very rapidly replacing them. Therefore, when your fuse box breaks down, it’s always a smart decision to replace them with consumer units due to the fact that they’re safer and also comply with building regulations while also being a lot easier to use. If you’re extending your home, upgrading to a larger capacity model enables you to make use of more power with the power overloading. In this post, we’re going to cover the amount you’re expected to pay to replace or install a new fuse box or consumer unit as well as the factors that may affect the cost.

For a 10 way dual RCD consumer unit, the typical cost range will be between £250 to £600, meanwhile 15 way dual RCD consumer unit should cost within the range of £300 to £700. Overall, the smaller the house, the fewer the circuits that’ll be needed, hence the difference in the aforementioned prices.

There a number of factors that can affect the cost of replacing a fuse box. These factors includes the the size of the house in question ( the bigger the house , the more the circuits there are and the bigger the fuse box needed), the location ( for instance, places like London where there are higher demands are likely to be more expensive than other regions ).
