How much electricity do I consume?
Prior to going ahead with installing a solar photovoltaic system, it is very important that you are aware of your household’s energy consumption. You should be able to attain this information from your electricity bill, this will be shown in the form of kilowatt-hours (kWh) or alternatively as units. If this information is not stated, then contact your local Energy Distribution Company, who should be able to provide it to you. Once you are aware of your energy consumption, you can then compare this against the potential yield of a solar system: As a guide, 1kW of PV should generate 4kW of electricity each day but this will vary depending on your location, the position and orientation of the system on your roof, and the seasons. A Solar Choice Broker will be able to assist in sizing a PV system that meets your needs.
How quickly do you want to see a return?
Obviously most people will answer, “as fast as reasonably possible”. Making a comparison between an investment in Solar energy with an investment in a Diesel/Petrol generating set. A standard rate of return on a smaller system (under 5kW) is usually expected to be under 5 years. On a larger system (5-10kW) the expected payback period is around 5-7 years. Although the initial up-front cost is considerably more, the long term benefits of these systems far outweigh that of a Generator systems.
Why is this particular system being recommended to you?
We can discuss with you what system sizes and configurations are best suited for your property, and what is best suited for you in terms of financial budget. We can discuss with them your energy usage and how much electricity can suitably serve your facility. Then, based on your budget and priorities we can provide you with a range of options. Ultimately, the choice is up to you.
Are warranties supported locally and how are warranty claims handled? What happens if something goes wrong with the panels?
As with any large consumer purchases, it is wise practice to confirm if there are valid warranties on your installations panels, inverters and overall installation. For example, if the panels are held by the manufacturer, it may be up to the customer to remove the panels from the roof and have them shipped to the manufacturer for testing, at their own expense.
Preferably the warranties should be held by the installer. This way, if something does go wrong the installer will be on hand to deal with problem. Which is why at Vesselnet we ensure every installation comes with valid warranties.
How will the system be maintained?
With very little maintenance, your new Solar system can last up to 25 or 30 years. There is very little maintenance associated with a grid-connected Solar installation system. All you need to do is keep the panels free and clear of debris and dirt accumulation, and have the electrical system and wiring regularly inspected periodically. That is why at Vesselnet we offer after sales services.
What racking (mounting) will be used and what is the warranty on the racking?
Standard racking components generally consist of the rail itself (annodised aluminum) and fasteners (stainless steel). The rail is made up of various clamps, plates and brackets. The racking warranty is included in the Installer’s warranty. As this is an integral part of the system, especially for very windy areas.
How long will it take from deposit to installation?
This factor will vary depending on your installation choice. Installation times vary and can range from as little as three weeks to four months. With flexible payment options available on selected Solar installations.
