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.

Are you thinking about installing a solar thermal system in your home? If yes, the you’d most likely be wondering the exact amount the system is going to cost. Well, you’re not alone. This is one of the most common question when it comes to solar thermal systems and we aim to answer that in this article. So let’s get started!

Unfortunately, the cost of a solar thermal system can’t be given in a single, accurate answer as they vary widely. However, when getting a new solar thermal system, you can expect to pay a sum within the range of £3000 to £6000 ( this includes a lowered VAT rate of 5 percent). The figures provided takes into account the installation costs as well as all the parts ( such as control panel, solar collectors, hot water tank and pipes).

To determine the price of your system, the quality and type of the panels matter. For instance, according to the Solar Trade Association, a properly insulated twin coil cylinder system would be priced at around £4500. in the same tone, it’s also possible to get DIY solar thermal kits that includes all the required hardware which will cost within the range of £1500 to £250. This however, may not be eligible for government support. In order to benefit from the RHI, your system must be fitted by a MCS accredited installer.

The varying prices of the solar thermal system’s initial cost is based on the specification of each individual house. For example, in situations where the building is having complicated water system, the plumbing cost is expected to increase which will have a serious impact on the overall cost of the solar thermal power system.

If your solar panels are mounted on your roof and you require a ladder to reach them we would always recommend you get a professional to do the work for your own safety.

If you’re thinking about installing a solar thermal system in your house, it’s always important to put into consideration numerous factors before you proceed. While some solar thermal systems are suitable for use at home, there are also some that are suitable for businesses or organizations which normally requires a big amount of hot water like hotels, restaurants, schools, hospitals and many more. You’ll also find some types available in the market that are suitable for communities to satisfy communal hot water demands.

It should, however, be noted that solar thermal systems do not have the capacity to produce all the hot water demand of a house. In the UK, an average household will need an annual water heating of between 3000kWh to 5000kWh. Whereas, a solar thermal system is only able to meet about 40 percent to 60 percent of this demand.

With that in mind, it’s also worth noting that during the summer months when the solar radiation is at its peak and hot water demand is relatively lower when compared to other seasons, a solar thermal system may be able to provide all of your household’s hot water needs. This implies that during this period you may not find the need to operate your boiler at all. However, during winter or colder months, when you have a higher hot water demands in contrary to a lower solar radiation, a solar thermal system will only be able to take care of about 20 percent of your household’s hot water needs. And that ultimately implies that during this period, you’ll need to rely more on a alternative or backup source of heat like gas, coal, electricity, oil or LPG.

After making the very important business decision to go solar, you may also want to know just how long it’ll take to complete the installation process and start generating electricity. After all, generating electricity is the main reason you made the switch to solar system. In this post, we’re going to provide you with in depth details on how long it takes to install solar panels as well as the factors that may affect that time.

The entire process of solar panels installation and getting them approved isn’t an overnight process. You’ll have to wait for periods for each step of the process whereby one must be completed before moving to the next. The time required to complete each step can, however, vary largely depending on your location, the type of solar panels you opt for, the solar company you hire as well as the number of people that’ll be making the installation. Here are the steps to a solar system installation and the estimated time each are expected to take:

• Site assessment. Once you chosen your solar company, the first step would be to have a solar professional from the company to visit the site to examine the roof and other features so as to make sure that they’re able to support a solar system. From the initial contact to scheduling the site visit, this step can take up to 1 to 2 weeks
• Local permitting. This involves getting the right permits from your local authorities. This can take up to 3 to 6 or more weeks.
• Solar system design. This may take up to a week or two depending on whether or not you need design approval and also where the parts are coming from
• Installation. This step can take a week or two depending on the size af your solar panel and roof.
• Inspection. This step can take up to a week depending on where you reside and how quickly the inspector can visit.
• Utility connection. Depending on your utility company, this step can take up to 2 weeks.

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.

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.

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.
