Commercial Solar Panels
What are the benefits of Commercial Solar?
Commercial Solar panels offer a fantastic addition to any business be it small or large. The obvious benefits of such an acquisition are:
- Reduced energy bills
- Benefit from state and federal incentives to reduce installation costs
- Prominent, public facing, projection of your green values
- Reduced CO2 output resulting in improved carbon accounting figures
- Generation of income from unused power in a number of states
- For larger installations you can achieve very good returns on investment
- Stabilise electric supply and reduce cooling overheads in summer.
State and Federal Incentives for Commercial Solar Panels
First of all, businesses can benefit from the federal tax credit that reduces the cost of installation by 30% straight off. Many states also provide their own incentives through rebates and tax credits that can make a big difference to the installation costs. Some states offer a feed in tariff that pays businesses for the excess energy they produce and many have net metering which allows commercial enterprises to reduce their energy costs.
Another thing that should be taken into account when considering installing a large scale commercial solar panel PV array is the aesthetic impact it will have on the surrounding area. Though less conspicuous than wind turbines, solar fields and rooftop arrays have still provoked some strong opposition by groups concerned over their effect on the landscape and local buildings.
Each state or county has its own planning and development legislation in place which you need to be sure of before undertaking a major installation of this kind. Getting permission is therefore a central consideration when thinking of installing a solar field, because unlike small domestic or commercial installations, all large scale projects will require planning approval from the local authority. The ultimate planning decision will be based on a range of factors, including visual impact (glare, etc.), the potential benefits it could bring to the local community, the array’s impact on the local ecosystem, as well as the local electricity grid connectivity. The good news is that many states are actively promoting solar, particularly large installation which contribute to reaching renewable portfolio standards.
Commercial Solar Fields and Farms
As well as being an attractive proposition for homes and business owners who want to save on energy bills and produce clean energy, solar PV technology is increasingly becoming a popular way of profiting from larger pieces of land. Fortunately, it’s something that the USA has plenty of.
More and more landowners across the US are installing PV panels on their land in the form of large scale (often up to several megawatts) solar fields (sometimes also called solar parks) in order to benefit from leasing arrangements with utility companies and incentives from state and federal sources. While this can be done through so-called ‘solar developers’, who install and maintain panels on a piece of land and then pay an annual rental fee, landowners and ranches can choose to have a PV installation company install the array and then arrange to sell the energy produced to electricity suppliers if the facility is available.
Naturally such schemes are especially popular with farmers, many of whom are looking to diversify their businesses as certain farming sectors become increasingly unprofitable. In many cases solar fields offer a more reliable source of income than that offered by traditional farming, as the return on investment is good and can guarantee a good income for a period of 25 years (the average life-span of an array). As with smaller systems, solar farms can, of course, also provide low-cost and low-carbon electricity for dwellings and other buildings in remote areas, particularly those off grid.
Though the exact amount of money to be earned from solar fields/parks depends largely on the amount of available land and other site-specific factors, the figures are often very attractive indeed. Businesses such as Coronal Development specialise in finding land they can lease from owners to install solar farms, paying a lease for periods of 20 to 25 years. For those landowners who chose to install the PV array themselves the income is sure to be even higher, though obviously this option presents a slightly higher financial risk.
Suitability for Commercial Solar Panels
Given the high upfront cost involved, the feasibility, development and planning processes required for large scale solar projects are usually lengthy and highly detailed. Substantial building or landscaping work may also be required. As with any other solar PV installation, in order for a site to be suitable it must usually meet certain conditions, such as:
- few obstacles (trees, hills, buildings, etc) which could cause shading issues and reduce the output of the array
- some PV developers may set a minimum area of land for it to be financially viable
- the proposed site must not be susceptible to floods
- flat or south sloping ground is optimal
- there must be access for initial construction and regular maintenance
- planning permission is unlikely to be granted for proposed sites located in protected areas
- there must be a local connection to the electricity grid
The solar field installation itself will comprise the PV panels, frames, inverters and cables, as well as security measures such as fencing and even cameras for some larger installations. There will also be a central control and monitoring hut.
Though regular checks of the array are required, PV panels have no moving parts, which make them reliable and durable. More information on the maintenance requirements of PV panels.
