Do you need a generator if you have solar panels?
If you have a solar power system, do you need a generator? The answer will depend on your situation and local electricity rates, but in general, if you have a battery bank to store excess energy from your panels, then a small generator can be an excellent way to free up that energy when it’s not being used.
For example, let’s say you have an average solar panel system with an output of 10 KW. Each day this will produce around 10 kWh of electricity which is about enough for one light bulb. An hour of sunshine on your rooftop might generate more than 10 kWh. But if there’s no cloud cover or the sun doesn’t come out at all for several hours, then only about 1 kWh will be produced.
Keeping track of all the hours of daylight and estimating how much energy is available from PV systems is very difficult for most people and it’s also very expensive.
What is a generator and how does it work?
A generator is a machine that converts mechanical energy into electrical energy. There are many different types of generators, from small portable units to large industrial machines. Generators produce electricity by rotating an armature inside a stator and magnetic field produced by electromagnets. The armature is powered by the engine or it can be wind-powered. In some cases, like on boats, the propeller can power the generator mechanically which is called a marine propulsion system.
Generators are typically rated to generate power at specific voltages and amperages and they are also size-based. So, as an example, if your battery bank has 100 amp hours of storage capacity then you would need a 100 amp hour rated generator to run your solar panels all day without having to worry about disconnecting them for use during the nighttime hours.
Types of generators
There are two types of generators: a Stand-alone generator and an Inverter generator. An inverter will convert your PV power into electricity that you can run appliances and electronics with. A stand-alone generator is an expensive unit because of the fuel needed to run it, but it’s much more compact than an inverter unit.
A stand-alone generator will also take up less space on your property. A stand-alone unit is easy to set up and maintain because there’s no need for complicated wiring or installation. You could also purchase a portable inverter generator that can be used when you travel or go camping or power outage in your area that prevents you from using your solar panels for electricity.
When do you need a generator?
A small generator is a great way to make sure you have a backup supply of energy in case your solar panels don’t produce enough. The generator will also help you take advantage of any wind, hydro, or other renewable energy sources that might be available.
However, before buying a small generator, consider how much excess electricity you will need to store. If it’s less than the capacity of your battery bank then you don’t need a generator and can just use your battery bank instead.
Selecting the right size generator for your needs
Many people underestimate the amount of electricity they consume. This means that a small generator that is used for only running the fridge or freezer for a few hours a day could be wasted during peak periods when your solar panels produce more energy than you need. If you want to be able to take advantage of using a smaller generator, then it’s best to estimate what you are going to need and make sure that you have enough battery storage capacity to match your consumption levels.
Having an excess of power can also save money in the long run as there are many energy retailers who offer a rebate for being connected to their network for 24 hours or longer every month. They will pay out around 40 cents per kWh which is an excellent way to offset some of the costs incurred due to not having a backed-up supply with your solar panels and have some extra cash stored in case there is ever a power outage or natural disasters such as an earthquake or bushfire
How to decide which brand is best for you?
If you’re looking for a generator to use with your solar panel system, then you’ll need to choose a brand that is compatible with your system. Ideally, you’ll have access to the technical specifications of the generator so that you can make an informed decision.
There are many factors to take into account when choosing which brand will be best for you. At first, it might seem like there are only a few brands on the market, but as time goes by more and more brands will enter the market. This means that it’s important to make sure that whichever generator you decide on has been tested and validated for your specific needs.
For example, if you live in an area where there is very little rainfall or where temperatures are very high during daytime hours, then there might not be enough moisture available from condensation from the air during cooler months so it’s important to get a generator with an efficient cooling system. If this is something that concerns you then consult with some experts about which generators will be best for your needs before purchase.
Generators v battery banks: Which is better?
A battery bank would be a better solution for many people, but not all. If you’re in an area with lots of cloud cover or if there are long power outages that last more than a few hours then a generator would be the best choice.
Generators are also easier to use and integrate into your system because they don’t require as much work from the user. You would just need to plug it into a power outlet and the generator will automatically start when it’s plugged in.
If you have battery banks for storing excess energy, then you would need to monitor them constantly during use so that they can stay charged up, which might mean significantly more work on your part. This could also lead to significant problems if say one of your batteries failed or if there was a problem with your solar panels. A generator doesn’t have this problem because it is self-powered.
When do you need a generator? A generator is a device that converts mechanical energy into electrical energy, which is why it’s called a generator. Generators are typically used to charge batteries and run equipment in remote locations. They can also be used to power your home, but they can’t run everything.
What can generators do? A generator might be the perfect solution for your needs, but before you make a purchase, it’s important to know exactly what you’ll be using it for.
Will you need a generator to charge batteries for an emergency power outage?
Will you need a generator to run critical equipment in an emergency? Will you need a generator for your home?
