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.

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.

Solar thermal panels work by capturing heat directly from the sun and using it to heat water. This hot water is then passed through a coil to heat the water for your central heating system. Solar thermal systems are compatible with many existing conventional boilers with hot water tanks, and can be set up to feed in to your existing heating system.

How Do Electric Boilers Work?

Electric boiler are installed in residential, commercial and industrial properties to serve as a reliable source of heat. Unlike other types of boilers that depends on fossil fuel burning to be able to operate, electric boilers are fuelled by electrical energy which ultimately makes it more reliable and powerful compared to its counterparts. This heating option was basically provided for home or property owners who don’t have an access to the main gas supply.

So how does an electric boiler work? Basically, an electric boiler work by heating water. Once heated, the hot water supply is then distributed to various areas across the house or property. In order to achieve the best possible efficiency at the lowest possible costs, new model electric boilers are installed by licensed and professional boiler fitters with the help of a microchip control system. Meanwhile, the microchip control system functions to oversee the management of both temperature level as well as output.

Unlike other types of boilers such as a gas boiler, electric boilers only require minimal service. If you own a gas boiler, it’s crucial to ensure that it’s serviced every single year by a licensed and reliable professional that’s into boiler repair services. During the checks and maintenance services, the gas boilers would need to be checked for possible gas leaks, as well as ventilation poisoning and other problems.

Overall, electric boilers are considered to be one of the most environment-friendly heating system which is more affordable to install in your property than a gas boiler. It represents the most ideal option for homes with gas boiler issues as well as those that are not connected to the main gas supply. What’s more? Electric boilers are also one of the best options for wet central heating and under floor heating.

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.

Asides from the fact that solar energy can be converted into electricity with the help of solar panels, there’s also another pretty cool way the sun’s power can be harnessed - solar thermal technologies. These technologies are able to convert sunlight into heat rather than power and these are in fact the very first solar energy products that were commercialized in the United Kingdom. Solar thermal panels, in a similar way to solar PVs, can help in minimizing your carbon footprint while also assisting you to save good money on your energy bills by providing the much needed coverage for your heating needs with the help of a renewable energy source that’s totally free.

Solar thermal panels provides some great benefits which is capable of making all homeowners in the UK consider installing one in their respective homes. Let’s take a closer look at these benefits.

✓ When compared to solar PV panels, they’re a more affordable heating option and also have a shorter payback period.

✓ Solar thermal panels are more efficient than PV panels due to the fact that the heat waves are able to hold more energy than sunlight and also because there’s no electricity transformation process.

✓ Solar thermal panels are able to operate in cold climates, strong wind as well as overcast weather, and make use of an energy storage system.

✓ They can help you save about 600kg of carbon dioxide emissions on an annual basis.

✓ Although most of the solar thermal panel systems come with a warranty usually within the range of 5 to 10 years, they’re able to last up to 25 years. What’s more? The require just a little maintenance, meaning the main cost you’d have to worry about is the cost of installation.

It’s always recommended to use a certified electrician to carry out electrical work. They can self-certify that their work meets building regulations. While some parts of electric heating systems can be installed as a DIY project, the thermostat and other control wiring legally must be installed by a certified electrician. There are a range of competent persons schemes in operation.
