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 constructed in the 1960s, where you’d probably need to rewire the entire house unless the wiring is the modern PVCu coated type, majority of houses built in the 1970s would not need to be rewired. Most often than not, what they’ll need is just a consumer unit as well as an earthing upgrade. If you happen to have a consumer unit change, the electrical professional you hire would have to inspect the most parts of the property regardless. With that answered, you may also wish to know just how often a house would need to be rewired.

First and foremost, in order to make sure that your wiring is safe there’s a need to ensure that a periodic inspection is carried out by a fully licensed and qualified electrician every 10 years. Meanwhile for rental properties with tenants, the landlord is required to carry out a periodic inspection at least every 5 years. This will make sure that the electrical works in the property are safe, up to date and suitable for continued usage.

In order to determine whether your house needs to be rewired, there are some signs or indicators you’d have to watch out for. If you notice one or even a combination of the following , then you should get in touch with a registered electrician:

• Discoloured outlets and switches
• Persistent burning smell
• Outlets problems
• Flickering lights
• Tripping circuit breaker or blown fuses
• If you happen to possess aluminium wiring
• If you have continually experienced electrical shocks

It must, however, be said that rewiring a house is a messy and quite disruptive work. It’s also considered to be quite dangerous and recommended to be carried out only by a professional is well trained and experienced when it comes to tackling electrical works.

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.

It might be possible to fit electrics in your shed, depending on where it is and what it’s made of. You should get in touch with a qualified electrician to find out whether it’s possible. Never attempt to run electrical cable from your house to an outbuilding!

Like every other systems in your home, solar hot water systems will require periodic inspections as well as a regular maintenance in order to keep it running as efficiently as it should. Not only that, the various components will also require either repair or replacement from time to time. It’ll also be proactive to take the necessary precautions so as to prevent worrying issues like corrosion, scaling or freezing.

Is it a task you can handle on your own? Well, there are some inspections and maintenance activities you should be able to handle on your own, however, you’ll also require a qualified technician to carry out the more technical or complicated tasks. You should also take note that it may actually be more cost effective to have some systems replaced, shut off or removed completely than having it repaired. Here are some of the essential inspections that should be carried out on solar system components. They include:

✓ Collector soiling. Periodic cleaning of your collectors is important especially in dry and dusty climates.

✓ Plumbing, ductwork and wire connections. Check the pipe connections for fluid leaks. Examine duct connections and seals. Also make sure that all wire connections are tight.

✓ Roof penetrations. Flashing and sealant around the roof penetration should be checked to see that it’s in a good shape.

✓ Collector shading. Check for shading of the collectors on annual basis as this may greatly affect their performance.

✓ Support structures. Examine all bolts and nuts which connects the support structures to the collectors for tightness.

✓ Heat transfer fluids. Anti freeze solutions in liquid solar heating collectors will have to be replaced periodically. And this right here is a task that’s best handled by a licensed technician.
