According to NASA, the sun produces 44 quadrillion watts of freely available power annually. This equals the output of 44 million large, pollution-producing power plants.
Solar energy is abundant, reliable, and environmentally friendly. This makes it the ultimate choice for commercial customers across the USA.
It’s an excellent source of reliable power during outages and infinitely renewable, but how do you take advantage of it for your business?
Keep reading to learn more about passive vs. active solar energy and how your business could benefit from these initiatives.
Types of Solar Energy
Solar energy is currently the fastest-growing power market worldwide. As such, it’s become more accessible and affordable than ever, with solar panel prices decreasing by 40% in the last ten years.
There are two ways your business can harness the power of solar energy by converting the sun’s rays into useful energy:
Active Solar Energy
Active solar energy devices capture solar radiation using photovoltaic cells as part of a solar panel setup. PV solar panels use semiconductor materials arranged within the panel to create a direct electric current.
When photons of sunlight strike these panels, the semiconductors release a stream of electrons. This creates an electric current that flows through the wiring in the PV panels to an inverter.
The inverter converts this direct current into an alternating current. Most commercial equipment runs on alternating current.
PV solar energy panels are usually roof-mounted at an angle that allows them to collect solar energy most efficiently. You can store excess energy in battery systems to make up for cloudy days or inclement weather.
Silicon-based monocrystalline, PERC, and polycrystalline solar panels are the best-known active solar energy examples.
You can also use thin-film solar panels to power your business. These PV panels use cadmium telluride, amorphous silicon, or copper indium gallium selenide to create an electric current.
Solar collectors work well in active solar systems. These devices use water or air to store energy in the form of heat.
You can distribute this heat throughout your premises via pumps, fans, air ducts, or blowers.
Passive Solar Energy
Passive solar energy options rely on the construction and structure of your building to function optimally. They’re usually used to convert the sun’s energy for heating and cooling.
You don’t need to install extra devices to take advantage of passive solar energy. They operate using the laws of thermodynamics.
Passive systems use collectors to draw energy from hot surfaces to the cooler surfaces of the collectors.
South-facing windows are one of the best ways to make use of the sun’s warming rays. You can make the most of them by installing double-pane or triple-pane highly insulative glass.
The following measures work well to complement your energy-efficient windows:
- Thick, insulated walls
- Vegetation to create shade
- Dark surfaces to optimize heat absorption
- Ceilings with external ventilation
- Cool roofs
You can use both active and passive solar energy in your business to cut costs and ensure a reliable source of energy.
The Pros and Cons of Passive vs. Active Solar Energy
Both active and passive solar systems are eco-friendly, sustainable energy sources. They help reduce carbon emissions and provide cost-effective energy for your commercial premises.
Each of them offers a few extra benefits, as follows:
Active Solar Energy Benefits
Active solar offers greater efficiency than passive solar does thanks to its mechanical elements. It usually has a higher capacity than passive solar does, too.
Unlike passive solar energy, your building’s design has little impact on how active solar operates. Solar energy companies can come up with solutions and retrofit them for almost any type of building.
You can connect your active solar system to the electrical grid to benefit from net metering and extra power when needed. You have more control over the electricity produced by an active solar power system.
Drawbacks of Active Solar Systems
Solar panels are a low-maintenance investment, but they do require a little ongoing maintenance. You must check your solar panels for damage regularly and arrange for a professional to clean them at least once a year.
Active solar technology is much more expensive than passive solar measures. The necessary equipment also takes up space inside and outside your building.
When you install an active solar system, you may need to acquire a permit from your local government. This process can be confusing, expensive, and take a long time.
You can enjoy federal rebates when you implement these systems. This helps reduce the expenses associated with active solar technology.
Why Use Passive Solar Power?
Passive solar power is an excellent way to reduce your building’s operational costs even further. By taking care of some heating and cooling tasks via passive means, you can use active solar-generated electricity for other things.
It’s an excellent option for smaller buildings with low heating and cooling needs. You typically don’t need any expensive technology to harness the power of passive solar energy.
Passive solar measures require no maintenance.
You can enjoy federal rebates by improving your building’s envelope with passive solar measures.
Negatives Associated with Passive Solar Energy
Unless your building is perfectly positioned, you might need to implement some expensive alterations to maximize passive solar energy. Passive solar relies heavily on the design, type, and placement of your windows, walls, and floors to perform at its best.
You have little control over the heat generated by solar energy. So, you could face overheating on very hot days or ineffective heating on very cold ones.
It’s sometimes difficult for installers to retrofit efficient passive solar measures for existing buildings.
