What Is Solar Home System

Energy Pricing And Incentives

Solar Power System For Home: Ultimate Beginners Guide

The political purpose of incentive policies for PV is to facilitate an initial small-scale deployment to begin to grow the industry, even where the cost of PV is significantly above grid parity, to allow the industry to achieve the economies of scale necessary to reach grid parity. The policies are implemented to promote national energy independence, high tech job creation and reduction of CO2 emissions. Three incentive mechanisms are often used in combination as investment subsidies: the authorities refund part of the cost of installation of the system, the electricity utility buys PV electricity from the producer under a multiyear contract at a guaranteed rate, and Solar Renewable Energy Certificates


With investment subsidies, the financial burden falls upon the taxpayer, while with feed-in tariffs the extra cost is distributed across the utilities’ customer bases. While the investment subsidy may be simpler to administer, the main argument in favour of feed-in tariffs is the encouragement of quality. Investment subsidies are paid out as a function of the nameplate capacity of the installed system and are independent of its actual power yield over time, thus rewarding the overstatement of power and tolerating poor durability and maintenance. Some electric companies offer rebates to their customers, such as Austin Energy in Texas, which offers $2.50/watt installed up to $15,000.

Understanding Australias Solar Rebate

Introduced in 2011, the Small-scale Renewable Energy Scheme was introduced to support the uptake of renewable energy in Australia. The SRES works by issuing Small-scale Technology Certificates to homes & businesses that install systems under 100 kilowatts in terms of the DC Solar Panel capacity. The STCs are officially created once a Clean Energy Council accredited Solar Installer has commissioned the system. The Solar Installer sells the STCs either on the market themselves or via a broker/aggregator, meaning the end-customer only needs to pay the difference.

Utility And Solar Meters

Youre probably familiar with a traditional electricity meter, which is what your utility company uses to measure your energy usage each month. But when you go solar, you will either need to replace your traditional meter or add a second one to measure how much solar energy you produce and send back to the utility.

Sunnova home solar system customers will have two meters:

  • Your Sunnova meter will measure your home solar production.
  • Your utility meter will measure how much utility electricity you use and how much solar energy you send back to your utility. If you have an older meter, you will need to get a dual direction meter from your utility.

Battery Storage

For greater energy independence by storing solar production and the added security of a backup power source for essential appliances during grid outages3, consider adding a battery to your home solar system. The way your battery is linked, or coupled, to your solar system will depend on the type of battery you use.

  • DC coupling: A battery-ready inverter is also known as a hybrid inverter. What makes it a hybrid is that its shared by both your solar panels and your battery. Since both components operate in DC power , there is no need for a second inverter specifically for the battery.
  • AC coupling: AC coupled systems have two inverters: one for the solar panels and one for the battery. This simply means your solar panels and your battery are both connected to their own inverters to produce usable AC power.

What Are The Different Ways To Use Active Solar Heating In Homes

There are 2 basic types of active solar panel heating systems solar air space heating and solar water heating systems .

#1 Solar air space heating

Solar air space heating directly heats your living space using room air heaters. A roof-mounted or wall-mounted air heater pulls cold air into a solar collector, where it is heated and then warm air is blown back into the room.

With roof-mounted heaters, ducts are used to push heated air into the room. And with wall-mounted room heaters placed on south-facing walls, holes are made through the wall in order for the air to pass into the room.

Since 2010, the US has produced some record-breaking solar air heating installations, with systems up to 10,000-50,000ft² being installed on a single wall.

#2 Solar water heating systems

Solar water heating systems have solar collectors that absorb solar radiation and convert it into heat. Either a non-toxic glycol antifreeze or water flows through the solar collectors so that the heat energy from collectors is transferred to the fluid.

As the liquid quickly passes through the solar collector, its temperature increases up to 10°20°F . The warm fluid then flows to a heat exchanger or a water storage tank.

There are 3 main types of liquid-based solar space heating systems radiant floor systems, hot-water baseboards, and central forced air systems. Lets find out how these systems work.

Solar Battery Charging Stations

SHS can either be stand-alone system or utility interactive with or without backup. Basically stand-alone systems include a solar panel that converts sunlight into DC power to charge a battery or set of batteries via a charge controller. The charge controller ensures that the battery is properly charged and discharged. DC appliances can be powered directly from the battery, but AC appliances require an inverter to convert the DC into AC power. As opposed to SHS, SBCS are primarily dedicated to charge batteries for more than one household. SBCS fall under two basic designs configurations

Charging outlets come from a common busbar, each outlet having a charge controller to prevent battery over-charging and a blocking diode to prevent battery current reversal.

One array of modules dedicated to one charge outlet, making a charge controller and blocking diode optional.

What is the Solar System?

Another element of concern is Díazs simplistic view regarding Ergons role in providing maintenance and operation of SHS. He paid no attention to the difficulty of sending technicians to cut power of a single SHS of a homeowner who has fallen behind on payment. Even more troublingly, his indifference toward whether or not a customer pays revealed that he sees Ergon as an independent, technical actor, with no recognition of its partnership with the public sector, nor the public distributors efforts at bill collection. He said,

Ergon, what it does is installs the system, it makes sure that the system is operational, whether the user pays or doesnt pay, Ergon is indifferent. Complying with its obligation, Ergon has to keep operative. If at any time the distributor says Hey, Ergon, cut their power, at that moment Ergon cuts off power, but the amount charged to cut power is not included in the operation, it is a separate charge.22

Incentives For Installing A Solar Heating And Cooling System

Not only are solar heating and cooling systems easier on monthly energy bills and better for the environment, they may also qualify for tax breaks. The best incentive available at the time of publication is a 26 percent federal investment tax credit . It directly offsets owed taxes and may even come back in the form of a tax refund.

When you file your federal tax returns, the current tax credit gives back 26 percent of the amount you paid for qualified systems placed in service after December 31, 2019, and before January 1, 2023. For systems placed in service after December 31, 2022, and before January 1, 2024, the ITC drops to 22 percent.

Additionally, some states and municipalities offer a variety of tax incentives and rebates for energy-efficient home appliances. Its worth investigating if youre thinking about making the switch.

Beware Of Cheap Solar

Inevitably once you start looking into solar you will start to come across some too good to be true prices for solar One Time Offer $2,500 for 6.6kW! We recommend treating these companies with caution as usually they are making major sacrifices on customer servicing, product quality and installation procedures. See this ABC coverage which covers some examples of what can go wrong.

They may be offering a 10 year + warranty on their installs or products but that warranty is only valuable to you if the company is still around and there is a clear Australian warranty claim process. We receive many phone calls from orphaned customers from years ago who are trying to contact Chinese factories to claim warranty.

Ultimately if it looks too cheap, it probably is, and a too cheap solution will cost you more in the long run than a well-priced system.

Always do you research on the solar installation company and the products they are offering. See our 5 questions you should ask your installer or or call us on 1300 787 273 if you need any help.

Will My Solar Panels Be Connected To The Grid What Is Net Metering

The vast majority of home solar systems will be connected to the grid. With grid-connected solar, net metering serves as an efficient solution to the question how will I power my solar home at night? Net metering is a solar incentive where you receive bill credits when your solar system overproduces electricity. During times when your panels arent producing enough electricity, like when the sun isnt shining, you can use those bill credits to cover the cost of your grid electricity use.

If you are off-grid, you wont have access to electricity from your utility. This means that, in order to build a completely off-grid project, you will need energy storage capabilities, an extra-large solar panel system, and provisions for backup power to cover you when your panels dont get enough sun.

Types Of Solar Panels

Rwanda tender: EDCL invites bidders to install solar home ...

Solar panels for home use come in two varieties: monocrystalline and polycrystalline.

Monocrystalline solar panels are made from a single silicon crystal. Such large and flat crystals do not occur naturally, and they are synthesized to make panels. Monocrystalline panels are more expensive than polycrystalline panels, but they are efficient. They can transform between 22% and 23% of the sunlight energy they receive into electricity.

Polycrystalline solar panels contain many small crystals fused together. They are more affordable than monocrystalline panels, but they are less efficient. They convert between 16% and 19% of sunlight into electricity.

If you have a large area in which to place your solar panels, you may decide to use polycrystalline panels because they are more affordable. You will be able to buy more for your money. However, if space is limited, monocrystalline panels are capable of producing more energy for their size and so may be preferable.

Quality Meets Efficiency And Sustainability

The Solar Home System project, which is implemented by atmosfair together with the young company fosera Manufacturing in Ethiopia, strives to effectively counteract this problem. Together, the project partners provide households with high quality yet affordable solar systems. In contrary to many mobile solar lamps, fosera is producing fixed installations, which can be supplemented with up to four lamps. One Solar Home System with two lamps can save approximately 0.25 t per year in comparison to the usage of kerosene lamps. fosera implements sales in the rural areas of Ethiopia with already existing seller and retailer networks.

atmosfair provides the financial resources for the project, which fosera only has to pay back partially. In return, the company guarantees to produce and distribute Solar Home Systems at a low market price. Until today, more than 13.000 systems have been produced and sold.

Many families in Ethiopia are happy when they can come home in the evening and operate a light switch. They also have the opportunity to recharge their mobile phones, because for many Ethiopians these are an elementary tool on which they depend for example for mobile banking. A further benefit for the households is the reduction of smoke pollution and the money saved in the long term, as they can now refrain of the use of kerosene lamps.

Basic Battery Cost Guide

As a general guide in Australia, a battery system will cost around $1000 per kWh installed, or in the USA its closer to US$700 per kWh. For example, the Tesla Powerwall 2 with 13.5kWh of storage capacity will cost around AU $14,500 fully installed, while the 9.8kWh LG RESU battery will cost closer to $8000 plus the additional costs of a compatible hybrid inverter and installation. There may also be additional costs and switchboard upgrades, especially if dedicated circuits are required to be backed up during a blackout. The battery location is also important and some households may require dedicated enclosures or covers to be installed to help protect the battery from extreme weather and direct sunlight which could result in overheating and shutdown. In some cases, the warranty may be void if the battery is not installed in a semi-protected location.
