Solar Repair & Maintenance For Commercial Facilities

Everything You Should Know About Solar Repair & Maintenance For Commercial Facilities

It has been forecast that by 2026, the global renewable power capacity will rise by more than 60% of what it was in 2020, measuring at around 4800 GW.

While all renewable energy sources are promising candidates for the future of power generation, solar panel systems appear to be the most preferred method due to their many advantages. This is evident by numerous studies; for instance, estimates show that around 95% of the global electricity generation capacity increment will be made through renewable sources, with solar accounting for more than half of it.

This widespread embracing of solar has led to exceptional developments in solar technology. More efficient manufacturing processes coupled with numerous incentives offered by the government have helped lower the cost of residential and commercial solar panel systems by as much as 70% in the last decade. This has directly resulted in a boom in the solar industry in the US, with there being over 10,000 different solar companies in the country having a total of more than 230,000 workers.

While residential property owners have immensely contributed to this massive shift towards solar and will continue to do so in the future, they aren’t the only ones taking part in this noble and innovative coalition. The benefits of solar energy have been widely acknowledged by many popular large-scale businesses who have joined in on this movement towards solar. Nearly 3.5% of all commercial buildings in the US have commercial solar panel systems.

Furthermore, around 70% of the commercial buildings in the US still draw their energy from their local utility, meaning that solar panels for businesses still have a largely untapped market. Following are some business giants that have gone solar in the past few years:

Commercial Solar Panel Systems – 6 Business Giants That Have Gone Solar

  • Securing a Local Permit for the Project (2-8 weeks)

Permission from the relevant authorities is secured, and applications for incentives are filed.

  • Designing the System and Planning the Installation (1-2 weeks)

The system will be designed using CAD software, and the construction plan will be finalized.

  • Installation (2-3 weeks)

The installation of the system takes place, which includes laying the wiring, mounting the panels, and connecting the inverter and batteries.

  • Inspection (1 week)

A final inspection is carried out to ensure that no regulations are breached and that the system operates properly.

Benefits of Commercial Solar Panel Systems

GO GREEN with Renewable Energy

Conventional power plants produce electricity using either fossil fuels or nuclear energy. The enormous amounts of carbon emissions released from thermal power plants have and still are severely harming the environment. Many habitats have been destroyed, forest fires have become more frequent, and abnormal climate shifts have occurred due to these emissions. Additionally, the nuclear waste from nuclear power plants is hazardous to the health of humans, animals, plants, and all other living matter.

By going solar, you can help substantially cut down the carbon emissions, even more so if you’re a business that operates through multiple facilities releasing large amounts of carbon pollutants into the atmosphere. This will help offset the dominance of carbon emissions, allowing the environment to better regulate the carbon content in the atmosphere and heal itself.

Attract Environmentally Conscious Residents, Employees and Clients

The importance of preserving the environment and reducing carbon imprints, as well as the use of non-renewable energy sources, is growing with each passing generation. Installing solar panels can help you attract customers, clients, residents, and representatives who are environmentally conscious and want to do business with or work for companies that value the planet’s well-being by reducing their reliance on non-sustainable power sources.

It can particularly assist you in growing your business by reaching environmental goals and partnering with worldwide businesses that prioritize such initiatives. Additionally, obtaining certifications from environmentalist organizations will improve your brand image and value.

Avoid Power Outages

When your facility operations are completely reliant on the municipal power grid, it is completely vulnerable to blackouts. When the electricity goes out due to a fault in the grid, a storm, or scheduled grid maintenance, your facilities also lose power.

However, if you have a self-sustaining commercial solar panel system with a battery for power storage and use, your spaces will not be without power during a local blackout. As long as the sun is shining and your battery backup is functioning properly, your panels will continue to provide electricity to your structure’s electrical infrastructure.

Reduce Operating Expenses

Regardless of whether or not your commercial solar system consists of a battery, you’ll surely have your utility bills go down. An on-grid system can help you save on utility bills in two ways. Firstly, the power produced by your system means that you’ll be drawing in less power from your utility, lowering your grid-sourced power consumption and hence the utility bill.

This becomes even more favorable if you completely shift to your commercial solar system during the on-peak hours, thereby cutting down your utility consumption to zero when the electricity rates are at their highest during the day. Secondly, any excess power generated by your system can be sold to the grid to further lower your utility bill.

Seeing as how businesses and corporate spaces have quite a heavy power consumption, going solar can considerably lower their operating cost, thereby improving your profitability, especially for large manufacturing facilities that operate heavy power-draining machinery.

Enhanced Property Value

If you plan to sell your business, a portion of your multi-unit private property, or factory in the future, solar panels can raise the value of your property and help it sell faster and for a better deal. It is solely because energy efficiency and productivity are valued.

When potential buyers see that your property can sustain its own electrical load or even just a portion of it, they will realize and acknowledge the fact that the operating cost of the property will be lower than for equally sized non-solar properties. This will inadvertently raise the market value of your property.

Better Control of Your Operating Cost

Electricity costs tend to change very often, following only an upward trend. However, with much of your energy needs being fulfilled by your own commercial solar panel system, your dependence on your municipal utility will be much less.

What this essentially means is that an increment in the cost of electricity will not affect your operating cost by much as it would without solar. This gives you better control over your operating cost allowing you to keep your net expense nearly steady and consistent while that of your non-solar competitors rises along with the cost of utility.

Longevity and Low Maintenance

The average lifespan of solar panels ranges between 25 to 30 years. This means that commercial solar panel systems far outlive their payback period, ensuring you a predictable and reliable energy output for an extended period of time.

Additionally, commercial solar panel systems, in general, do not have any moving parts. Therefore, you do not have to trouble yourself with complex and expensive maintenance procedures, as you would with a wind for example.

However, you will still need to schedule periodic checkups with your solar company to ensure that the electronic equipment in the panels such as the diodes and solar cells are functioning properly. Weekly cleanups of the solar panels coupled with a semi-annually or annually company checkups would be all the maintenance you would need.

Of course, the frequency of cleaning may vary depending on the weather and your location. Overall, a prolonged lifespan combined with easy-to-maintain nature makes solar a very cost-effective and feasible approach to renewable energy. Even more so if you are located in a place with an abundance of sunny days, as is the case for most of California.

Solar for Small Businesses – Is It Feasible?

There isn’t one right answer to this question. Whether or not solar for small businesses is a viable option or not depends on the type of business, their power consumption, and their location. Many businesses and commercial spaces across the US don’t spend enough on electricity to make solar a worthwhile investment.

According to Forbes, nearly 25% of commercial spaces and buildings in the US are not suitable for solar due to their low power consumption. However, if your business does use up a lot of power and is located in a sunny-majority area, solar might be a promising option for you. To know for sure, get in touch with a professional solar company that deals in solar panels for businesses and get your property evaluated.
