An attic fan acts as a ventilation system that decreases the temperature in your attic by releasing hot air and bringing cool air in.
Temperature is reduced, and your air-conditioner is not overworked because the cool air decreases the temperature in your attic, so there is less heat going through your roof.
You do not need to keep your solar attic fan up and running all the time. You need a solar fan when direct sunlight goes on your roof tiles to make space underneath hot. Your solar fans start to function when the sun shines on the solar panel, which generates energy.

Being able to handle erratic voltages flowing out of solar panels is very important for the goal of harnessing the energy output of this abundant source. As light changes, so does the energy flowing from your solar panel. The problem is, however, electrical current around the world has little variable range, of 3-5% depending on the current. To help mediate this issue, a solar charge controller steps up to the plate.
What is a Solar Charge Controller?
The perfect equipment to store solar energy is called a solar charge controller. A solar charge controller is basically a regulator that transfers power from the PV array to the battery bank and system loads.
Also, Solar Charge Controllers regulates the voltage when the battery is fully charged to protect them from undercharging or overcharging. This is a crucial role since solar charge controller batteries can be expensive.
Solar charge controllers come in handy during a power outage, during winter, or when you want to store power for night use. However, not all solar charge controllers are the same. That is why we compiled a list of tips on how you can choose the perfect solar energy controller for your equipment.
What to Look for in a Solar Charge Controller
Selecting the perfect solar charge controller is crucial to match your needs. If you want to control a system wherever you are, you will need to check the performance and reliability of your controller. Even when you are on a budget, it is important to make sure that the solar charge controllers meet important charging requirements.
When you settle with cheap and ill-performing controllers, your risk running into future problems like high expenses, loss of operating time, and you might need to make a lot of site visitations.
Read on to know what to look for in Solar Charge Controllers.
Design of the Solar Charge Controller
The design is an important consideration to keep in mind when selecting a solar charge controller is the design. The design of solar charge controllers is highly important since they are always exposed to high temperatures.
With this in mind, it is recommendable for smaller charge controllers to have no fans since they benefit from simple passive cooling. Some of the advantages of a fanless solar charge controller include:
High Dependability– Since fans are designed with moving parts; they are likely to cause problems for the solar charge controller. For this reason, fanless controllers work better.
Longer Lifespan- Fans are more likely to trap insects, dust, and dirt. When this happens, the controllers will get clogged and this will inevitably shorten their lifespan.
Higher Efficiency- Since fans use electricity from the solar panels, it acts as a parasite to the charge controller. They divert and consume solar power that could have been used in more important things.
There are larger charge controllers that make use of passive cooling technology without the aid of fans. These controllers have highly advanced thermal-mechanical software and design. They are also best suited for remote systems and you won’t need to worry about maintenance.
Another tip is to ensure that the settings of the controller are compatible with your system’s needs. Preset charge settings are often present in smaller solar charge controllers. Therefore, it is a good idea to choose a controller with a lot of settings options.
There are also charge controllers that allow you to customize the settings to adjust to a certain set of voltage points. If your system does not cycle as required, you can set it up with less time in daily absorptions. This is the same length of time before the battery is used.
Examine the Lighting Options
If you don’t want to be bothered by setting up the lights in your solar charge controllers, you may want to choose ones that you can freely customize the daily lighting control settings. With this kind of control, you can easily adjust the lighting on/off setting according to your needs.
You don’t have to worry about manually turning on the lights when it gets dark or turning it off in the morning. Make sure that the device can do this automatically to make your work easy.
When choosing the right solar charge controller, it is highly crucial to think about what it is for, how big or small you want it be, how much you are willing to spend, and where you want to install it.
All these things must coincide to avoid facing any possible problems in the future. The quality and reliability of the solar charge controller should not be overlooked since it serves as the energy storage once your solar equipment runs out of energy.
Have some questions about solar? Here are some frequently-asked inquiries:
1. Will the solar energy system protect me from grid outages?
Not all the time. Especially during grid maintenance, your panels need to be shut down to protect electricians. It’s the reason why you should have a battery included in your solar power system for a continuous electric flow at home or in commercial spaces.
2. Why do fewer people use battery packs?
They aren’t as available and affordable, unlike other solar energy system components. It’s also worth considering when you go for solar energy system packages as they include battery packs in them.
3. Is there a constant need to replace solar panels?
Only for maintenance, but it’s a rare occasion. Most panels last up to fifty years. Also, they are only replaced when external forces damage them.
4. Will solar panels damage the roof?
Not at all. If the quality is excellent, your roof should hold the panels fine with less damage to the shingles or trusses.

What is Solar PV?
Photovoltaics (PV or solar electric) is the technology behind solar power. It’s the module system inside every panel that converts sunlight into electricity.
What’s Inside Every Solar Panel?
Solar panels are made of conductive silicon modules that produce electricity when exposed to light. They have a positive and negative layer that creates an electric field like a battery. Once sunlight hits these modules, it converts the energy to DC and flows it to the inverter. Then, the inverter converts DC to AC which is now usable for power consumption.
Why is Solar Power Right for You? What are its Drawbacks?
Solar installation is safe. It undergoes full quality inspections and testing before use. Also, only a qualified and expert technician can do the process. Its renewable, low-cost energy production gives you leverage on electric power, with only its upfront costs and space consumption as its drawback. Solar power isn’t also a good option in areas with low sunlight and places with frequent weather changes.
Everyone knows that solar energy is the power source of the future, but do you know it is also an excellent saving on your bills? The big question is, how much does solar power save?
Based on the Solar Industry Energy Association (SIEA) statement, there are a million homes in the US now using solar power in 2016. The number of households using solar power is even growing in numbers this year. There will be four million homes in three years that’ll use solar energy as their power source.
What Makes it an Affordable and Cost-Effective Power Source?
Solar panel systems cost around $15K to install, but it delivers measurable and controllable energy within your budget. It means you only need to spend one time and save up from detaching yourself from the grid with lesser power to support your appliances and electronics.
Plus, electricity costs are rising every year. So, having an alternative energy source to power your home can offset electric bills by more than 30%. Also, solar power can increase property value and store some electricity that you don’t use or when you’re away from home.
