| About Electricity... | ||||||||||||
| What is Electricity? |
||||||||||||
| Energy is around us in a variety of forms, which include, to name just a few, gasoline, running water, light and electricity. We often transfer energy from one form to another, for example, when an automobile uses the chemical energy in fuel to move. Some types of energy are easy to store (i.e. chemical) and others are easy to move from one place to another (i.e. electricity and light). Electricity is one form of energy that we have harnessed in the past 100 years. By definition, electricity is the energy available from the movement of electrons within a conducting material. It is analogous to water flowing out of a hose; the electrons are like drops of water. Enough electrons with force behind them can perform useful work. Amp hours and watt hours... In power systems we describe the total amount of energy consumed over a certain period in either amp hours or watt hours. A one amp current draw for 4 hours has used a total of 4 amp hours (AHr). A 100 watt light bulb over 24 hours uses 2400 watt hours (WHr) or 2.4 kilowatt hours (kWHr) of energy. Note: a kilowatt equals 1000 watts, and a kilowatt hour equals 1000 watt hours. Your local hydro utility charges per kilowatt hour used. |
|
|||||||||||
AC versus DC current... Just to make things interesting, electrical energy is moved from place to place in two ways. Alternating current (AC) is the most common form; utility power arrives to us as high voltage AC current. Alternating current is like water sloshing back and forth in a bath, the same electrons doing the work in one spot. Solar panels and batteries produce direct current (DC), which is easier to store. DC current is usually used at lower voltages, i.e. 12 or 24 VDC. |
||||||||||||
Inverters convert DC to AC power… You may choose to install an inverter to complete your power system. An inverter converts battery energy, which is DC power, to AC power, so that regular 120 volt appliances will operate. An inverter allows you to you use microwaves, toasters and TVs without a generator. The Inverter section of this catalogue lists many models that are suitable for installation in homes, cottages, RVs and at industrial sites. |
||||||||||||
Advantages of higher voltages... In all power systems we have to move the electricity from one place to another. The transfer is not 100% efficient, and we must take care to minimize the power losses en route. In wire, the loss of electrical power is a factor of the resistance of the wire, and the amount of current going through it. In general, for a given wire size, the lower the current and in turn, the lower the power loss. Appliance Power Ratings* |

| Solar charging systems for recreation vehicles | ||
| Each year thousands of people install solar
charging systems on their RVs. Why? A solar system can put an end to battery worries, allowing you to dry camp without giving up the luxury of electricity. From simple battery maintenance to full-time live-aboard power, Excess Energy Solar RV Kits come in a range of sizes, and can be installed on RVs, campers, trailers, 5th wheels and motorhomes. |
||
| Choosing a solar charger kit... The selection of a power system starts with a look at your current power needs and the type of camping you enjoy (i.e. weekend, extended or full-time). If your power demands increase for any reason, solar systems are easily expanded. Excess Energy staff and Excess Energy Authorized Dealers can help you find the Kit that best suits your needs. |

* To calculate typical summertime charge rate, assume
5-7 hours of bright sun will shine on the solar panel. For example, an
RV-SH-75 with a Rated Current of 4.4 amps, times 6 hours, times 7 days,
will deliver 185 amp hours per week.
RV Power Systems & Inverters The Inverter section of this catalogue lists many models that are suitable for installation in RVs. This includes Go Power! Inverters with sizes from 300 to 2500 watts. Go Power! Inverters can feed AC power through all the RV’s electrical circuits, so that all outlets will have power 24 hours a day. |

| About Grid-Tie... | ||||
| Solar power systems for homes with utility power | ||||
| Many people choose to generate some of their own electricity
and reduce their dependence on the utility. A small solar system will “slow
the meter down”, reducing the monthly hydro bill. A larger system
may ”turn the meter backwards”, so that during the day, excess power is sold back to the utility. In any case, producing your own green power is not only satisfying, but can protect you during a power failure as well. |
 |
|||
The economics of grid-tie systems... At first glance the costs of generating your own power are expensive compared to buying it from your local utility. In Canada, we have some of the lowest power costs in the world. However, there are other motivating factors for installing an independent power system. The past years have reminded us that utility power cannot be taken for granted. After storms, many people can be without power for days. A solar system can act as a back-up, operating critical equipment in a home in the event of a power failure. A solar system can also fulfill the desire of many people to have some degree of independence from the utility, and the satisfaction of using an environmentallyfriendly technology. Green house gas emissions are a concern and most utilities generate a large portion of their power from fossil fuels. But the technology exists for you to take advantage of a free, non-polluting energy source - the sun! |
 |
||||||||
| Types of grid tie systems... Basic Grid-Tie: A solar array produces power during the day, and an inverter synchronizes this power with that supplied by the utility. Your home uses solar energy first, and draws whatever else it needs from your utility. At night, the utility supplies 100% of your power. |
|||||||||
 |
Grid-Tie + Backup: Your solar system functions
the same way as a basic grid tie system, delivering power to your home during
the day. But your system also has battery storage. In the event of grid
power failure, your inverter switches to battery power to supply your home’s needs. This keeps your important equipment running during outages or brownouts. |

Xantrex GT2548 Inverter GT inverters convert the power from a solar array directly into 240 VAC, synchronized with your utility grid power. They are a simple and easy way to add solar to any building already connected to the grid. The GT produces 2500 watts. The optional meter displays inverter output history. Two year warranty.

Using solar energy reduces dependency on the electrical utility and lowers monthly power bills. Excess Energy has experience with a variety of grid tie projects and has served as both supplier and general contractor. We have worked closely with architects, electrical engineers and utility staff to successfully integrate solar into buildings in projects across Canada. Here are some examples from our grid tie portfolio: |
||||||
 |
Saskatchewan Science Centre (2.8 kW) Excess Energy provided a turn-key 2.8 kW PV system to the Science Centre in Regina. The solar array was installed on the roof of the building, which incidentally was a former diesel generating station. The Xantrex Technologies inverter system produces three-phase power. This system was installed as part of a working display to educate the public on the potential for renewable energies. |

This simple system feeds synchronous solar power directly
into your home, so that instead of buying power from a utility, you will produce all or a portion of your own electricity. The Grid Tie System has two components: the Green Power Base Kit and the Green Power 600. The Base Kit includes the SMA Sunny Boy 1.8 kW PV grid tie inverter that converts the DC power of your solar array to AC power, and feeds your home’s distribution panel, without the use of batteries. Maximum power point tracking ensures that all the solar power you generate gets utilized. At night, your home draws power from the utility grid. Up to three Green Power 600 Solar Kits can be added to the Base Kit for a total of 1800 watts of solar power! Each Green Power 600 Kit includes a 600 watt solar array, roof-mounting structure, all necessary wiring and a safety disconnect. |

| Grid Tie/Back-up Power System | ||||||
 |
The Grid Tie / Back-up System offers both the
benefit of solar generation and the security of back-up power in the event of a power failure. During the day it converts solar power into AC power and feeds directly into your home. It also maintains a battery reservoir of 10 kWHr, and if grid power fails, you have enough backup power to run essential loads like furnaces and refrigerators for several days or more. This system is ideal if you live in an area prone to power outages. The Grid Tie / Back-up System combines an inverter, battery bank and a Green Power 600 watt solar array kit. The battery bank may be doubled or tripled for those who encounter long power outages. Also, up to six Green Power 600 kits may be added to the base package, for a peak total of 3600 watts! |

| Would you like to be a Green Power Pioneer? While there are tens of thousands of grid tie solar systems installed in the US, this is a relatively new concept in Canada. Every province has only a handful of homes using solar and utility power together, and Excess Energy and its manufacturers would like to change this. The Solar Pioneers Program is a joint subsidy program which helps defray the costs of installing a solar system on residences now supplied by grid power. Our goal is to have several systems installed in each Canadian province over the next 12 months. Qualified applicants will be asked to participate in a monitoring program and have their home showcased on our Solar Pioneers web site. Together we can change how Canadians look at power generation. Install a Green Power system on your home and show the rest of Canada what green power can do for us all! For more information contact us at vern@excessenergy.net |

| Back-up Power | ||||||||||
 |
Using Inverters for Back-up Power... An inverter converts stored battery power to 120 VAC. In a renewable energy system, such as a solar or wind system, inverters are used to provide power in remote locations. But the same equipment can be used to provide power to backup equipment found in offices, suburban homes or at your desk. What do I need to build a backup system? There are four components to a back-up system: |
|||||||||
|
||||||||||
 |
Choose a Back-up System that includes an inverter with transfer
switch and battery charger with enough power to handle the type of equipment
you want to run. If you don’t know how much power you’ll need,
see the table on Page 2. The battery bank is selected with enough reserve
storage to power your equipment for as long as needed, typically one to
48 hours. Excess Energy or its’ Dealers can calculate the battery bank size, if you need advice. Note that many of the inverters we offer have built-in automatic transfer switching to detect a power failure and connect the inverter to the load circuits. If some of the loads you wish to run are sensitive to power output quality, you may elect to use a pure sine wave inverter. |
|||||||||
| How do I install a Back-up
Power System? A Back-up Power System consists of an inverter, with a battery charger and battery bank. Smaller systems can be installed near the loads they will run - i.e. the computer or the furnace. Larger systems are typically installed in a basement or garage, near the electrical panels. The electrical circuits that are to be run from the inverter must be separated and wired through the inverter. For home backup systems, a small AC sub-panel for the emergency loads can be installed next to the main panel (as shown above). Don’t forget to enclose the batteries and vent them to the outdoors. Excess Energy has designed many back-up power packages for different applications. If you have any questions about the choice of a system to fit your needs, please contact Excess Energy or your local Dealer. |
