Solar Panel Installer FAQs

how much energy does a solar panel produce?

If you’re looking to purchase and install a solar system for your home or property, then knowing the amount of energy a solar panel can produce can go a long way to help you determine just how much solar panels that’ll be needed to power your entire house. In this article, we’ll give you an idea of the amount of energy that can be generated by a solar panel to help you make informed decisions going ahead.

First and foremost, you should note that each and every solar panel is rated by how much direct current power they’re able to generate under standard testing conditions. The output of a solar panel is given in watts units (W) and it stands for the theoretical power generation of the panel under direct sunlight as well as temperature conditions. Generally, several domestic solar panels possesses power output ratings which ranges from 250 watts to 400 watts. And as you would have expected, the higher power ratings are preferable when compared to the lower power ratings. What’s more? The total wattage of your solar panels will greatly influence a major part of your overall solar system cost.

Assuming you’re able to get just about 5 hours of direct sunlight every day, you can determine the output of your solar panel in this way - 5 hours x 290 watts ( wattage example of a premium solar panel) = 1450 watts-hours or approximately 1.5 kilowatts per hour (kWh). hence, the individual solar panel output in your array should be able to generate about 500 to 550 kWh of energy every year. This is sufficient energy to power some small appliances without problems.

What are solar panels made of?

Solar panels are made up of photovoltaic (PV) cells. These cells are made from silicon semiconductors, which absorb sunlight and convert it into electricity.

There are three main types of PV cell: monocrystalline solar cells, polycrystalline solar cells, and thin film solar cells. Monocrystalline cells are usually the most efficient and expensive, and thin film solar cells are the cheapest and least efficient. These are all made from silicone, but are manufactured in different ways.

How long do home solar batteries last?
How long home solar batteries last depends on the type of battery you have and how often it’s charged and discharged (when electricity is fed into it, then used later on). Generally speaking, a home solar battery should last between 5 and 15 years. Lithium-ion batteries last longer than lead acid batteries. Lithium-ion batteries are more common these days because they’re more cost effective. A lead acid battery is the cheaper option at around £2,000, but it’s likely to last between 5-8 years. On the other hand, a lithium-ion battery may set you back around £4,000, but will last between 11-15 years. So you can see that it’s well worth choosing a lithium-ion home solar battery. It’s also worth considering that a solar battery’s lifespan will be reduced if you over-discharge it. When your home solar battery is installed, you’ll be left a manual which will tell you its depth of discharge, or DoD. This means how much you can use the battery before recharging it – it's not as simple as letting the battery run down to 0% then charging it again. In fact, this can significantly shorten your battery’s lifespan. If your solar battery system’s DoD is 80% and its capacity is 5kW, make sure you charge it before you use up 4kW to help prolong its life. Luckily, most lithium-ion batteries have a DoD of 80% or more, so you don’t need to worry about not being able to use much of the electricity stored in your home solar battery. This is another reason to use them over lead acid batteries, because their DoD can be as low as 50%.

How Much To Install Solar Panels And Battery?

Are you thinking about installing solar panels and battery in your home and wondering how much the installation is going to cost? Well, you’re not alone. This is one of the most commonly asked questions in the solar world, but unfortunately a precise answer can not be provided. This is mainly due to the fact that solar panel systems come in varying sizes which is the main influencing factor that determines how much electricity that can be generated. In other words, the larger the system, the more the electricity that’ll be produced to your home’s benefit.

Generally, for a solar system size of 1kW, the average cost of the solar panel ranges between £1800 to £1850, 2kW is between £3600 to £3700, solar panel size of 3kW ranges between £5500 to £5600 and finally, 4kW is between £6000 to £6050. For example, with the aforementioned prices in mind, the cost of solar panels for a standard 3 bedroom house will range between £5520 to £6040 as the high electricity demands will need the installation of 3 to 4kW solar system size.

Meanwhile the installation cost of solar batteries is also dependent on a number of influencing factors like the size as well as the make of the battery. Generally, you can expect to spend within the range of £500 to £2000 to install your batteries depending on aforementioned factors. In the event whereby you’ll be retrofitting, you might also need to include an additional cost of £1000 for an inverter. However, it’s important to note that there are only quite a few hybrid systems which are able to combine a battery storage with an inverter.

How much do solar batteries cost?
How much solar batteries cost depends on the brand and type of battery and its capacity. At the moment, the cost is quite high because the technology is still new – but they will probably reduce, just like we saw the cost of solar panels reduce as the technology became more popular. It’s a great idea to get a solar battery installed with your solar panel system if you’re out most of the day. If you didn’t have a battery, all that electricity would simply go to the National Grid – but if you have a storage system, then while your solar panels are generating electricity in the day, it would get stored in the battery ready for you to use when you get home. Lithium-ion solar batteries are the most widely-used ones at the moment because they generally have a higher capacity and are more cost-effective. For a 3-4kWh battery, which would store enough electricity for a typical 4kW solar panel system, it will set you back an average of £3,400. If you need a larger battery, it could cost anywhere up to £6,000. Lead acid batteries are cheaper, and it can seem tempting to ask an installer to fit one for you – but they aren’t cheaper in the long run. While a 4kWh lead acid battery may only cost around £2,000, their life cycle is only around 1,800 cycles. A lithium-ion battery that costs around £4,000 would have a life cycle of about 4,000 cycles. That means that while the upfront cost is more, you won’t have to replace it as quickly as a lead acid one.
How long will a solar panel battery last once it's dark?

If you’re thinking about installing a solar system in your home or property, this is probably one of the things you’d like to know before making a purchase decision. Well, you’ve come to the right place! In this post, we’re going to give you a good insight into this to help you make the best informed decision possible moving forward. Let’s take a look!

First and foremost, it must be stated that providing a short and accurate answer to this question is nearly impossible as the amount of time a solar panel will last after dark is influenced by a number of factors. These factors include the size of your solar system, the battery size as well as your power usage. As you would have imagined, batteries are charged when there is excess energy that’s being produced by your solar system but it’s not being incorporated to power your home or property. More often than not, this occurs during the sunlight’s peak periods from about 10am to 2pm.

The time it’ll take for your battery to charge is influenced by the size of your solar system in Kilowatts, the size of your battery as well as the rate in which your system is being used. Your battery can be charged in a day or two, of course unless it’s an over-sized battery for your system.

When the sun sets and your solar panels can no longer directly run your appliances via electricity generation, the battery then kicks in. You will use about 1 to 2 kW’s of power if you’re watching TV, using the oven as well as lights internet etc. in other words, even a small solar panel battery will last all night. However, the same doesn’t apply if you’re having a party with running floodlights, three fridges and air conditioner as the battery will drain a lot faster.

Is solar energy renewable?

Solar energy is renewable, as the sunlight it uses won’t run out. This means that it’s a great way to generate electricity without damaging the planet. So, installing solar panels to generate solar energy can be a great move for businesses looking to reduce their carbon emissions.

how many solar panels can i fit commercial buildings?

Are you currently weighting the possibilities of adding a solar system to your commercial building? With lots of commercial property owners in the UK using solar now, many more are gradually coming to terms with the numerous benefits they stand to derive by getting one. Therefore, if you’re thinking about adding the system to your commercial building but do not know where to start, you’ve come to the right place.

 

In this post, our aim is to help you calculate the number of solar panels you’ll need to power your entire commercial building. Starting from the panels, you can begin by taking into account everything that makes use of power in your commercial building to get a good idea of how many you’ll need.

  • To get started, you’ll have to determine the number of watts used by your commercial building. To get this, you simply have to go through your utility bill for kilowatt-hours (kWh). This varies amongst buildings and being able to identify your daily average energy usage will assist you in getting your solar panel needs.
  • Once done, you’ll also 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.

 

In general, a medium-sized commercial building making use of an average amount of electricity will require about 70 average quality solar panels so as to cover its entire electricity needs. These are, however, just averages, so yours could be more or less so getting the idea is vital here.
