Five Considerations for your Commercial Solar Panels
When selecting a solar energy system that is right for you and your business, there are many factors that you should keep in mind.
To give a brief intro into what a solar energy system actually does, solar panels produce electricity from the sun through converting sunlight into electricity using the photovoltaic (PV) effect. The installation of a solar energy system will entail the mounting of panels on the roof, generally in a north to northwest direction. Solar power is in great demand and around one in four domestic properties. If you decide to sell or rent out your home or business premises, a solar panel system is a popular feature and may add market value.
Before deciding to install solar panels at your business or local community facilities, there are some important things that you may need to consider.
1. Facility assessments
To select the right panels for property, your solar technician will need to assess the roof space available and the system options suitable for you.
When considering particular systems that might be suited to your business or home, take your time to weigh up the cost and return on investment of each system type. At New Generation Solar we provide well-informed recommendations for suitable systems for you, and we can order in a particular system to suit your needs.
There are initial start-up and set-up costs of a home solar power system. But it’s worth looking at the upfront expenditure as an investment, as there are many ongoing benefits for owners that make up for the initial cost.
Our assessments provide you with the background to make the right decision for you, your company and your budget.
2. Understand Why Sizes Matters
Some solar installers focus on the size of their inverters to over-exaggerate the power of a particular system. However, at New Generation Solar, we know that inverter size isn’t everything.
We pair your solar panels with a suitable size of inverter, to cost-effectively boost the energy generation that your business can achieve. While having a larger inverter can be of benefit as you may be able to add more panels at a later date, this point can be discussed in your facility assessment with our technicians.
3. Solar Panel Quality
When comparing inverters, one of the most important things to consider is the inverter efficiency. Unlike solar panel efficiency, which, somewhat counter intuitively, does not directly affect the amount of electricity your solar system will produce, All the power from every solar panel goes through your inverter, so the amount of energy that your solar system generates is totally dependent of your inverter efficiency. The higher the inverter efficiency, the more power you’ll get and the more money you’ll save.
When we are planning the components and installation of your solar power system, we take into consideration:
- Panel voltage output
- Panel, inverter and wiring quality
- Strength of mounting solution
- Resistance to weather
- Optimum positioning to eliminate panels getting dirty
- Inverter and panel matching
4. Shade Tolerance
It is often said that solar panels aren’t a great investment on a shady roof. It is important for majority of the panels to be in sunlight, with only partial shading.
Solar panels and shade simply don’t mix. While some panels claim to be shade tolerant, you will lose substantial charging power even if only a partial area of the panels is affected by shade. Return on investment is higher when the solar panels are installed to receive direct sunlight in peak hours.
Depending on the set up, an entire string of solar panels’ ability to generate electricity can be affected by shading of a single module.
5. Component Durability & Warranties
Other important considerations for solar panels are the warranty period and any certifications the solar panel might have.
The guaranteed durability or longevity of a solar panel is important for a number of reasons – it can be an indicator of the manufacturer’s confidence in its products. Reputable solar panels will have warranty a period of 25 years.
