Complete Stand-Alone Solar Electric Power Systems

The solar electric energy systems on this page are examples of our complete stand-alone solar power systems complete with the charge controllers, disconnects, & an inverter, mounted & pre-wired.

We also have systems designed strictly for utility intertie applications that use no batteries and are designed to enable net metering (lowering your power bill) with your utility company. We can work with your contractor or architect for developing specifications on a system for your project.

The budgetary examples below of stand-alone type systems include solar panels ready-to-mount with all mounts & mounting hardware. Batteries are not included. The wiring needed for connecting the modules to the control panel & from the control panel to the batteries is not included. A gas or diesel burning generator may be used with these systems, if desired, to add electricity for days when heavier electrical use than normal occurs. Wind generators may also be used in the same system to boost your power input.

All of our systems' equipment components are designed to meet NEC (National Electric Code) requirements and use ULŪ listed system components.

While installing the pre-engineered hardware is straightforward for anyone capable, we can only recommend that you have a qualified electrician connect the wiring. Although it is not overly complicated, the safety factor should always take precedence in proper wiring of any electrical system or appliance. A section of the NEC code is dedicated to photovoltaic systems, and another on DC wiring. The components' wiring specifications are supplied from the manufacturer on each component. We are capable of designing and handling the installations of the systems we sell world-wide.

Solar modules used in these systems produce DC current and are available in sizes from 80 to 235 watts. Each module is individually tested and labeled with a 20 or 25-year output warranty by their respective manufacturers. These solar panels can be mounted using your choice of roof, ground, or top-of-pole mounts. This hardware system and the modules it supports are rated to withstand winds up to 125 MPH and up to 1 inch hail.

We also design complete solar electric systems using the following brands: Sharp, BP, Shell, Kyocera, and Evergreen. The life expectancy of a solar electric panel is 40+ years.

Your local area's average full sun hours per day multiplied by the system's rated output wattage will be close to the average electrical power yield per day. Full sun hours equate to kWH/meterē on these maps. Line and storage system losses must also be calculated-we do that. You can use the link below to find your area's average full sun hours.

To determine which system is right for you, you'll need to determine what your power requirements are. See the Calculators page or let us help you. You'll also need to know the average full sun hours for your geographic location. Full sun hours are equivalent to kW/hrs/meterē on these maps. There are roughly 1,700 available sunlight hours per year in Chattanooga, TN.

If your total AC loads that are to be run simultaneously should exceed the 4000 watt continuous rated output of the inverter we can stack two interfaced for greater peak output capacity. These systems are equipped with one Xantrex SW4000 inverter. An electric-crank fossil-fuel generator may be automatically cranked by a generator controller when a user-determined low battery voltage level is sensed. The inverter has a built-in efficient battery charger that will quickly charge the battery bank from a gas, propane, or diesel generator's 120 volt output if/when needed. A system can be designed for higher continuous and surge output using larger inverters. The complete power center is now ULŪ Listed.

If your power requirements are not met by one of these systems, we will be happy to custom design a system to meet your specific needs! See the Calculators page to assist in estimating your energy needs (watt hours per day).

Remember: Rated array output X full sun hours per day equals approximate average watt hours/day production.

Using the most energy efficient appliances available and compact fluorescent lighting is critical to keep your system cost reasonable.

Remember - You can light three rooms with compact fluorescent bulbs using the same electricity as you would to light one room with an average incandescent bulb!

*These were typical averages for flush roof mounting on pitched shingle or metal roofs. Actual installed costs have changed and will vary depending on site requirements and the proper mounting methods required. Battery banks must be sized and priced separately for stand alone systems. Most systems we sell are designed for specific needs and the above examples are only for rough budgetary estimating. We supply contractors with competitive wholesale pricing.
