Solar Electric

As of early 2016, most U.S homeowners are paying $3 to $4 per watt to install a solar panel system, and the average price of solar in the U.S. is $3.70 per watt. That's 12 percent lower than it was a year ago, and solar panel system costs are continuing to fall. However, to really understand what a single solar panel will cost and what a complete solar system will cost, it's important to compare prices quoted to homeowners in your area – total costs can vary depending on the state that you live in. Average cost of solar panels based on system size knowing the average cost per watt is helpful, but what does $3.70/watt actually mean for you? The cost of installing solar on your home or business depends on how much electricity you want to generate – a bigger system will cost more, because you'll need to buy more equipment and more labor will be needed to install it. The average solar energy system size in the U.S is approximately 5 kilowatts (kW). Based on the average price of $3.70/watt, a 5kW system would cost $13,000 after tax credits. Below are some average 2015 quotes for other solar energy systems by size: 6kW solar energy system cost: $15,600 8kW solar energy system cost: $20,700 10kW solar energy system cost: $26,000 These prices reflect the cost of a solar energy system after deducting the federal solar tax credit, which reduces your solar system cost by 30%. Some states, local governments, and utilities also offer rebates and other tax incentives that can further reduce the solar system costs in your quotes from solar installers.

Grid Tie Solar Electric Systems

Grid Tie solar systems are the most predominate kind of system for residential and business customers since it requires the least amount of equipment and the relies on the electric grid for nighttime usage. This type of setup also allows for excess solar energy not used during the day to be sent to the grid for credit against your nighttime usage. Unless you live in Austin, TX is not yet pro solar unlike the West coast and East coast states that have positive solar policies in place.

Distributed Generation (DG) refers to small-scale power generation (i.e. solar, wind, micro hydro) at a customer's home, or business, used to reduce the customer's need for power from the utility power grid. You will need to download or ask your utility for requirements and the documentation that must be submitted in order to "interconnect" with the electrical supply provided by your local electric provider. Each one has their own version and may require excess insurance as well. GreenTechFusion helps customers with the Utility Interconnection application and design diagrams required for a fee of $350.

Energy Efficiency

We always recomend before making a large large investment purchase like solar, to make your home or business energy efficient first which lowers your overall monthly electric bill and then we can resize your system after the energy efficiencies have been put in place..

There are a number of efficient things you can do for you home or business, to many to list so here are the top ones to focus on.

Off Grid Solar

An off-grid system has several different features as well. This type of solar electric system is not connected to the electrical grid. Instead, it relies on batteries to store the electricity generated by the solar panels for use when the system is not generating enough to sustain household functions, for example, at night. Because it is completely separate from the electrical grid, the power will remain on for the household or building even in the event of a widespread power outage; in a grid-tied scenario, the solar power system must shut off during a power outage for safety reasons. However, it is important to consider the space required to store the batteries, as well the added expense to purchase them. Additionally, off-grid systems cannot take advantage of SRECs, because the electricity never flows back to the utility grid.

Mobile & Emergency Solar Systems

In the past two decades, non-disaster-related electricity blackouts have increased by 124% in the US. These numbers are further compounded by the increasing incidence of large disasters that knock out power for extended periods of time in the US and longer wait times before you see your electricity back on. Furthermore, lots of folks have been in situations where grid power is either not available or impractical at the location in need.

Portable solar generators and hybrid emergency backup systems can be solutions to the increasing power reliability issues. However, there are some key points that must be addressed for the success and efficiency of such products. These critical ideas include the current state of fuel-based generators, trends in solar, understanding kwh and electricity terminology, the benefits of solar power, rethinking your power usage, measuring that usage, incorporating hybrid systems for prolonged activity, and utilizing knowledge to make informed buying decisions.

Solar Tracking Systems

Solar trackers are rising in popularity, but not everyone understands the complete benefits and potential drawbacks of the system. Solar panel tracking solutions are a more advanced technology for mounting photovoltaic panels. Stationary mounts, which hold panels in a fixed position, can have their productivity compromised when the sun passes to a less-than-optimal angle. Compensating for this, solar trackers automatically move to "track" the progress of the sun across the sky, thereby maximizing output.

Domestic Hot
Water Systems

Solar hot water systems and electric or propane/gas tankless hot water systems.

Solar thermal hot water systems can typically be cheaper overall than solar eletric system

Water heated by the sun is used in various ways. While perhaps best known in a residential setting to provide domestic hot water, solar hot water also has industrial applications, e.g. to generate electricity. Designs suitable for hot climates can be much simpler and cheaper, and can be considered an appropriate technology for these places. The global solar thermal market is dominated by China, Europe, Japan and India.
Tankelss hot water systems are becoming more popular in the USA and have been used in Europe and Asia for many years. Tankless systems are more efficient than tank base systems since they are not continually heating water and wasting energy. They are on demand systems and can be used in all electric or with propane or natural gas if preferred. Tankless electric systems are 220v AC and require quite a lot of electricity for short periods.

Integrated Collector Storage

Flat-plate and twin-tube evacuated collectors that are designed with the tank attached are also classified as ICS units. These designs depend upon thermosyphoning, where hotter liquids "rise" and colder "fall" as long as the storage tank is higher than the collector. ICS units are completely passive and don't depend on any moving parts or electricity to operate, though some contain electric water-heating elements for backup.


Thermosiphon (or thermosyphon) is a method of passive heat exchange, based on natural convection, which circulates a fluid without the necessity of a mechanical pump. Thermosiphoning is used for circulation of liquids and volatile gases in heating and cooling applications such as heat pumps, water heaters, boilers and furnaces.

Direct & Indirect Systems

Direct or open loop systems circulate potable water through the collectors. They are relatively cheap but can have drawbacks. Indirect or closed loop systems use a heat exchanger that separates the potable water from the fluid, known as the "heat-transfer fluid" (HTF), that circulates through the collector.

Passive & Acive Systems

Passive systems rely on heat-driven convection or heat pipes to circulate water or heating fluid in the system. Passive solar water heating systems cost less and have extremely low or no maintenance, but the efficiency of a passive system is significantly lower than that of an active system. Overheating and freezing are major concerns. Active systems use one or more pumps to circulate water and/or heating fluid in the system.

Drainback System

A drainback system is an indirect active system where the HTF (almost always pure water) circulates through the collector, being driven by a pump. The collector piping is not pressurized and includes an open drainback reservoir that is contained in conditioned or semi-conditioned space. If the pump is switched off, the HTF drains into the drainback reservoir and none remains in the collector. Since the system relies upon being able to drain properly, all piping above the drainback tank, including the collectors, must slope downward in the direction of the drainback tank.
