    What System is Best for me?<\/b><\/p>\n

    When choosing to invest in a solar system for your home or business there are several factors to consider.<\/p>\n

    First and foremost is deciding which is the best solution for you, your home or your business.<\/p>\n

    Our PERL Electrical Solar Experts will discuss each of the following options with you.\u00a0 Once the best solar solution for your needs has been chosen, our design team will design your system.<\/p>\n

    \n\t\tSolar Options\n\t<\/h2>\n\t\t\t\t\"Pasted\n\t

    Grid-Tied System<\/b><\/p>\n

    A grid-connected solar power system is the simplest, most cost effective and often provides the best returns on your investment.\u00a0<\/p>\n

    A grid-connected solar power system will utilise your generated solar power during sunlight hours and export excess solar power to the grid.\u00a0 When the sun goes down and your solar panels are no longer generating the system will switch back over to the grid (traditional electricity supply).\u00a0<\/p>\n

    This system is best if you have reasonable day time usage and \/ or able to load shift appliances to operate throughout the day i.e. washer \/ dryer, hot water, swimming pool, spa pool, EV charges etc.\u00a0<\/p>\n\t

    Hybrid System<\/b><\/p>\n

    Put into simple terms, a solar hybrid, solar and battery storage system allows you to use the surplus energy that your solar system creates during the day for use after the sun goes down rather than exporting your excess power back to the grid. The surplus solar energy generated but not used in the daytime is stored in batteries which are programmed to switch on as required so you can self-consume as much free energy as possible.<\/p>\n

    A grid connected solar and battery storage system will automatically switch over to the electricity grid once you have discharged the solar energy from the batteries.\u00a0<\/p>\n

    The hybrid system is still connected to the grid which acts as the systems ‘back up’ which is a significant additional benefit is back up power in event of a power outage.\u00a0<\/p>\n

    This system is best if the majority of your power usage is outside of sunlight hours and\/or you experience regular power outages.\u00a0<\/p>\n\t

    Off-Grid System<\/b><\/p>\n

    Off-Grid systems have no connection to the grid and therefore require battery storage to power appliances when solar panels aren’t generating enough power due to a lack of sun light.\u00a0<\/p>\n

    If you are to go “Off-Grid” it is vital that you fully understand your power usage and appliance load to correctly size your battery storage to last at least 1 – 2 days without recharging.\u00a0 Additionally it is recommended that the system is integrated with a back-up generator to ensure that you are prepared for all potential situations.\u00a0<\/p>\n

    While these systems can be complex and expensive, often, they’re more cost effective than running power lines to remote areas so are a potentially a good investment for farms in more isolated locations or marine islands where connection to the national grid isn’t available or is price inhibitive.<\/p>\n\t\t\t\t\"Pasted\n

    \n\t\tHow To Size an Off-Grid Solar Power System Correctly?\n\t<\/h2>\n\t

    PERL Electrical Solar power designers require detailed information about your daily power use. This is to ensure that the solar power system being installed will be right the fit for your home or business.<\/p>\n

    They need to know all of the appliances in the household that will be running from day to\u00a0day,\u00a0and the wattage of each appliance.<\/p>\n

    Our PERL Electrical Solar Power designers estimate the sun hours your location will receive in summer, along with the sunshine hours during the peak of winter. Also factored in are miscellaneous considerations, such as shade etc.<\/p>\n

    Engineers use the same information; this allows them to design a system size that will give you enough power for the shortest day of winter.<\/p>\n

    Should you require it, and depending on your budget, you could increase the recommended system size to have extra power; useful if you ever have visitors or a large family\/business.<\/p>\n

    Below are examples of common system sizes, and what they could potentially power.<\/p>\n

    Please note this is a rough guide, we recommend a system size developed to your specific power requirements.<\/p>\n

    \n\t\tHow MUCH DOES SOLAR POWER COST?\n\t<\/h2>\n\t

    Solar power system prices are largely dependent on the system’s size and the type of roof the system is installed on.\u00a0 Below is a small sample of residential system sizes in New Zealand and their typical pricing.<\/p>\n

    Prices were last updated on 04\/10\/2022.<\/p>\n\t

    *Please only use these prices as a guide.\u00a0 The solar power system prices assume straightforward installation on a metal roof.\u00a0Prices can vary based on a number of factors<\/a>.<\/p>\n\t

    Solar Battery Prices<\/b><\/p>\n

    Batteries can be used to store solar power for use at night, during times of peak electricity demand and during\u00a0blackouts<\/a>. Learn more about\u00a0solar batteries here.<\/a><\/p>\n

    Prices for a\u00a0battery storage<\/a>\u00a0system accompanying a grid-connected solar power system will largely depend on the battery’s storage capacity, followed by the brand’s reputation, quality and special features.<\/p>\n

    Generally, the more storage capacity is installed, the more expensive it is.\u00a0 Find out if\u00a0solar batteries are worth the cost<\/a>\u00a0or see the approximate prices for lithium-ion solar batteries.<\/p>\n\t

    \n\t\tSOLAR POWER AND OFF GRID – Frequently Asked Questions\n\t<\/h2>\n\t\t\t\tWhat other factors that may affect the Total Price?\n\t\t\t\t

    Different Roof Types Will Affect the Final Price<\/b><\/p>\n

    Installing a system on a metal\/tin roof is generally easier and uses fewer components, therefore has a lower cost. Tile, bitumen and shingle roofs are likely to have a higher solar panel installation cost due to the extra mounting components. Tilting panels to a higher angle on flat roofs might be a requirement that could also infer extra cost.<\/p>\n

    Other Factors That May Affect the Total Price<\/b><\/p>\n
