The Solution

HES PV designed a Gid-Tie PV system with battery backup. The 10kW Sharp solar array features high-efficiency mono-crystalline solar panels securely mounted on aluminum racks on the house’s flat roof. In the electrical room, a sealed, maintenance-free battery bank is kept charged. The 12kW inverter system converts the solar power to 240VAC and synchronizes the output with utility power. The house uses solar power first and any excess results in a credit from BC Hydro as part of the Net Metering program. In the event of a power failure, the battery system can run the house for weeks on end

Grid-Tied Solar Systems

Grid-tied, on-grid, utility-interactive, grid intertie and grid backfeeding are all terms used to describe the same concept – a solar system that is connected to the utility power grid.

Advantages of Grid-Tied Systems

1. Save more money with net metering

A grid-connection will allow you to save more money with solar panels through better efficiency rates, net metering, plus lower equipment and installation costs:

Batteries, and other stand-alone equipment, are required for a fully functional off-grid solar system and add to costs as well as maintenance. Grid-tied solar systems are therefore generally cheaper and simpler to install.

Your solar panels will often generate more electricity than what you are capable of consuming. With net metering, homeowners can put this excess electricity onto the utility grid instead of storing it themselves with batteries.

Net metering (or feed-in tariff schemes in some countries) play an important role in how solar power is incentivized. Without it, residential solar systems would be much less feasible from a financial point of view.

Many utility companies are committed to buying electricity from homeowners at the same rate as they sell it themselves.

 

2. The utility grid is a virtual battery

Electricity has to be spent in real time. However, it can be temporarily stored as other forms of energy (e.g. chemical energy in batteries). Energy storage typically comes with significant losses.

The electric power grid is in many ways also a battery, without the need for maintenance or replacements, and with much better efficiency rates. In other words, more electricity (and more money) goes to waste with conventional battery systems.

According to EIA data[1], national, annual electricity transmission and distribution losses average about 7% of the electricity that is transmitted in the United States.

Additional perks of being grid-tied include access to backup power from the utility grid (in case your solar system stop generating electricity for one reason or another). At the same time you help to mitigate the utility company`s peak load. As a result, the efficiency of our electrical system as a whole goes up.

 

Equipment for Grid-Tied Solar Systems

There are a few key differences between the equipment needed for grid-tied, off-grid and hybrid solar systems. Standard grid-tied solar systems rely on the following components:

  • Grid-Tie Inverter (GTI) or Micro-Inverters
  • Power Meter

 

Grid-Tie Inverter (GTI)

What is the job of a solar inverter? They regulate the voltage and current received from your solar panels. Direct current (DC) from your solar panels is converted into alternating current (AC), which is the type of current that is utilized by the majority of electrical appliances.

In addition to this, grid-tie inverters, also known as grid-interactive or synchronous inverters, synchronize the phase and frequency of the current to fit the utility grid (nominally 60Hz). The output voltage is also adjusted slightly higher than the grid voltage in order for excess electricity to flow outwards to the grid.

 

Micro-Inverters

Micro-inverters go on the back of each solar panel, as opposed to one central inverter that typically takes on the entire solar array.

There has recently been a lot of debate on whether micro-inverters are better than central (string) inverters.

Micro-inverters are certainly more expensive, but in many cases yield higher efficiency rates.Homeowners who are suspect to shading issues should definitely look into if micro-inverters are better in their situation.

 

What is Solar Net Metering (Net Billing)?

Residential and small commercial solar systems are connected to the load centre in a home or business. Solar generated electricity is used first, and utility power provides when solar cannot. If there is excess solar power generated, the power is exported back to the utility. Net Metering defines the process where a utility wheels your solar power to and from your system, essentially storing it for you. Sometimes this is a credit of kWh per kWh, or a monetary credit at a fixed rate per kWh (Net Billing). Net Metering programs enhance the value of solar to customers, and set the rules as to how solar may be interconnected with your utility.

Further more the amount you pay for solar on your house adds to the value of your house . Eg; if you wanted to sell your house with solar installed  and your neighbor has the identical house without solar also for sale , I know which house that i would buy ! 

Power Meter

Most homeowners will need to replace their current power meter with one that is compatible with net metering. This device, often called a net meter or a two-way meter, is capable of measuring power going in both directions, from the grid to your house and vice versa.

You should consult with your local utility company and see what net metering options you have. In some places, the utility company issues a power meter for free and pay full price for the electricity you generate; however, this is not always the case.

Solar ENERGY

From an environmental perspective, solar power is the best thing going. A 1.5 kilowatt PV system will keep more than 110,000 pounds of carbon dioxide, the chief greenhouse gas, out of the atmosphere over the next 25 years. The same solar system will also prevent the need to burn 60,000 pounds of coal. With solar, there's no acid rain, no urban smog, no pollution of any kind.

Mankind has been crazy to have not bothered to harness the sun's energy until now. Think about this. Go outside on a sunny day. The light falling on your face left the Sun just 8 minutes go. In that 8 minutes it traveled 93 million miles. Those photons are hauling and when they strike your PV module you can convert that motion to electricity. As technology, photovoltaics are not as glitzy as that new sport utility vehicle the television tells us to crave. But in many ways PV is a much more elegant and sophisticated technology.

Whether it be for your business or for your home, why not invest in Solar Panels.Today's solar panels are bombproof and often come with a 25 year warranty or more. Your solar panels may outlive you. They are also modular—you can start with a small system and expand it over time. Solar panels are light (weighing about 20 pounds), so if you move you can take the system with you.
