On Grid Solar Paqnels
Grid-tied or grid connected solar is a solar electricity system without batteries. Your home is hooked up to both the national grid and your Power Smart solar electricity system, so you will always have electricity available at the flick of a switch; even at night, or if it is cloudy. You can install a solar electricity system of any size and you will only ever be billed if your power consumption is in excess of the amount you are generating.
The electricity grid acts as a 100% efficient and maintenance free battery while also providing unlimited ‘on demand’ energy. This is what makes grid connected solar electricity so attractive. It has all the benefits of being attached to the electricity grid but with a portion of your electricity bill never increasing in price.
Off Grid Solar Panels
When the utility power is unavailable or too expensive to bring in to your home or cabin, solar panels allow you to be your own utility company! You can live in peace, with no noisy gas generator to disturb the quiet. There are several variations of off-grid solar power, depending on your needs and budget.
All variations of off-grid solar power depend on solar electric panels and store electricity in a bank of batteries.
Off-grid solar power also stores DC electricity in batteries. The addition of an inverter allows this system to convert DC electrical current coming from the batteries into AC or alternating current. AC is the standard form of electricity for anything that "plugs in" to utility power and is the appropriate current for common household appliances.
While AC off-grid solar power systems are more expensive because of the cost of the inverter, the appliances you are able to use are less expensive and there are more kinds of appliances to choose from.
