WHAT SIZE SOLAR SYSTEM SHOULD YOU INSTALL?
THANK YOU for taking the initiative and exploring the benefits of investing in a Solar Photovoltaic (PV) system designed and installed by Velocity Solar.
Attached is the PV system recommended for you, based on the preferences and information you have provided. You have the ability to alter and adjust any aspect of your pricing quote as required by accessing our website again and entering your email and pin number.
Our pricing tool will require you to provide your preferences for:
- System sizing
- Batteries (if applicable)
- Site specific information
Generally, the size of the solar system depends on the following:
- Electricity consumption and energy needs
- Availability of physical and unshaded area with maximum exposure to sunlight
- Incentives and Tariffs available
- Budget available
- Network limitations (Network infrastructure limitations)
Briefly analyse your energy bill
Most energy providers in Australia give a graph behind all your energy bills, stating the average daily energy utilisation. This is the key in deciding the amount of energy your property needs and the solar energy production required. It is also important to keep in consideration the sunlight your area receives on average/day. According to our calculations, a 1kW solar power system can produce 4kWh to 5kWh energy per day, but every site is different and no 2 sites are identical. The electricity consumption and determination of energy needs is important to estimate the solar energy you are expected to produce through solar energy applications from Solar Central, Our expert designing team have come from the solar field and technicians in the industry not just salesmen allowing us to give a better gauged expectation on what may be achievable.
Estimate electricity used during the day
Designing the system where solar panels are capable of meeting your energy needs only in the daytime (sunrise to sunset where the panels will be operational), unless you have battery storage or a generous solar feed-in tariff. The solar energy has maximum utility only when it is used directly and decreases the amount of electricity purchased from the retailer. So, it is very critical to estimate the total electricity consumption during the day, when the panels can have maximum exposure to the sunlight.
Calculate how much energy can be self consumed
There is a possibility to sell the excess electricity back to the grid, but it is equally important to understand the financial incentives included. These offers are generally very low and it is advisable to gain the most from the solar system through self consumption. If your looking at solar power from a environmental aspect then it may be feasible to look at your whole production but this needs to be assessed prior to installing. Solar Central helps all the clients to choose the system which would suit the energy consumption and energy required during the day and night, respectively.
Your long term plans
Whether you are planning to expand the family or the house – the factors are needed to be considered to estimate your energy requirements and ultimately decide what size of solar system can be installed for you. Upgrades are available for all the solar systems, but installing a correct size in the very beginning is more cost effective. Upsizing inverters for future production has been going on for years but even this needs to be looked at carefully as if not designed correctly you may end up paying for a bigger inverter but the extra capacity will not be worth the label written on it. Make sure your get a qualified and experienced designer to help make these decisions as your system is a long term investment and decisions more today will impact for many years to come.
How much roof space is available?
In the current times, the solar systems are allowing great flexibility in design and installation. They can be installed on the roof, in the roof and as a flat roof landscape or portrait arrangement. With the flexibility allowed, the size suitable for you will also depend on the roof space available in your property. Panels have come a long way a standard 210 watt panel 4-5 years ago is now 260 watt standard with options of getting a 320 + watt panel with some technology on the market. So if your limited on roof space the more efficient panels can give a greater energy yield and open opportunities.
Analyse how much you can spend for the solar system
The affordability of the solar system is increasing, as the large scale global installations have decreased the manufacturing costs and affordability. The prices deviate from one part of Australia to the other, but below is an estimated price you might end up paying for the specified size of solar system you need.
