Products

We provide Grid-Tied Net Metering systems, Grid-Interactive systems, and Off-Grid systems with battery backup. We offer three types of systems

Solar Electric (PV) Systems Wind Turbine Systems Solar Thermal Heating Systems

3.1 Solar Electric

(PV) Systems

Using no moving parts, solar photovoltaic modules

capture the tremendous energy in sunlight and turn

it into electricity. An inverter converts this DC

electricity into clean AC power that feeds your

building’s electrical system. With Net Metering, any

excess power that is generated is fed back onto the

local power grid, causing your electric meter to turn

slower or even run backwards! You will

automatically be provided credit for this surplus by

your utility company. At night and on overcast days,

you’ll draw on utility company power just like you

do now. A number of grid-interactive backup options

are available using battery banks.

Benefits

Reduce your utility bills with clean,

sustainable power

New technologies enable use of solar

power by more homes and businesses

Sharp residential solar modules provide

a smart, attractive addition

Government incentives are available to

significantly reduce system costs

3. 2 Wind

Wind Turbine Power Systems

Benefits Wind Turbines can lower your electric bill by up to 60 to 90 percent State grants and Federal tax incentives can offet a significant portion of the cost Help generate clean, affordable energy

If you have a viable wind site (annual average wind speed over 11 mph), you may want to consider this resource. Dovetail can assist you in determining the average wind speed for your site. Many Midwest sites have seasonably strong winds (especially during the winter) that favor a hybrid system combing wind power with solar PV to achieve more consistent year-round generation. Solar PV's higher summer output picks up just about the time that wind speeds begin to drop off during warmer months.

Dovetail is an approved Eligible Residential Wind Installer for Ohio Energy Office grants.

Dovetail provides small to mid-size wind turbines (from 1 kW to 250 kW). We regularly research available turbines from around the world seeking the most efficient, reliable, cost effective turbines. We currently feature Xzeres Wind, Evance, Kestrel, Proven and Southwest Windpower wind turbines. These are the best machines we have found for the low to moderate wind speeds that are commonly found throughout Ohio and the surrounding states.

3.3 Solar Thermal

Solar Thermal Heating

Benefits 50%-70% reduction in energy for water

heating

Typical payback 5-10 years - even less with

state and federal incentives!

Works in any home or business

Solar radiation is unevenly distributed throughout the

year, greater in the summer, lesser in the winter.

Transforming solar radiation into usable energy is a

function of temperature; the higher required

temperature, the lower the efficiency even of the best

insulated collector. In the case of water heating, the

threshold temperature for delivery of useful solar

energy is low with incoming water temperature,

typically at 55° to 60° F (13° to 15° C). Moreover, the

interaction of the supply of sunshine and the demand

for hot water is very fortunate: the daily hot water load

is fairly constant throughout the year so that all

available sunshine can be profitably used for immediate

consumption.

Solar Thermal energy can provide a large

percentage of your hot water needs and

reduce by 50% to 70% the energy consumed

by your existing system. It provides

substantial savings for both residential and

commercial buildings. Typical payback time

for solar thermal systems range from 5-10

years - even faster with state incentives and

Federal tax credits.

Types of Systems Solar Hot Water

Solar Pool Heating

Solar Space Heating

Dovetail primarily designs solar thermal

systems utilizing flat-plate solar

collectors from Heliodyne and Schuco.

We also offer high temperature

evacuated tubes from Apricus and

Sundra in a variety of configurations.

Heliodyne is one of the oldest and most respected firms in the solar

energy industry. They have a solid reputation for providing

unexcelled equipment and service at a competitive cost. Heliodyne

provides complete solar energy systems, not just the collectors.

Solid engineering has gone into designing these systems and

matching all components. Dovetail works with Heliodyne to size your

system; to provide the optimal system to satisfy your particular

requirements. Heliodyne manufactured systems also offer the

advantage of simplicity of design and construction. Dovetail does

not need to worry about compatibility of parts, and can concentrate

on providing you a professional installation. This is a very crucial

point in the overall economic efficiency of your system.

The Heliodyne heat transfer and control

modules, called HELIO-PAKS, are engineered with

reliability and simplicity in mind. Dovetail has

experience with HELIO-PAKS of different sizes

and configurations. We recognized early that the

proper heat transfer module is a crucial part in a

solar energy system and selected the HELIO-PAK

line. Problems of maintenance (i.e. fouling), poor

performance (i.e. incorrect flow rates), as well as

outright break-downs (i.e. freezing) are all

connected with poorly designed systems.

Our most popular systems are closed-loop

systems. We use direct PV powered pumps

and AC powered pumps with differential

controllers. Both types of systems are easily

applied to a home or commercial building.

Most are designed to operate year round,

while some pool heating systems are used

only in summer months.

Solar Thermal Features Systems are reliable, and offer trouble-free performance for years.

Solar Hot Water Collectors work in any part of the country and in

every season.

Creates clean power – reduces pollution.

Heat exchanger can attach directly to your existing electric hot water

tank.

Solar Thermal systems can provide 100% of your heat for domestic

hot water in the Summer, and 40% to 70% in the Spring and Fall, of

the while using utility electric or gas for supplemental secondary

heating during these seasons. In the Midwest, Solar Thermal provides

from 10% to 30% of your heat energy in winter months.

Pool and Spa owners see huge savings on heating bills and can enjoy

the pool earlier in the spring and later in the fall.

Heated water can also be used to heat living space.

Solar Thermal is especially cost-effective at facilities such as

restaurant kitchens, laundries or camp showers that use large

quantities of hot water.

4.0 Market analysis

summary

Site Analysis and Design

In order to develop a firm proposal for

a system tailored to meet your specific

goals and building characteristics, we

typically need to visit your location and

perform a site visit. During a solar site

visit, we determine the system

requirements, the best location, measure

the sun & shading characteristics, where

to locate the inverter, breakers, wire

routing, system tie-in, etc.. During a

wind site visit, we ascertain similar

requirements, plus the parameters for a

wind turbine, and the best location,

height, and type of tower. A solar thermal

site visit, enables us to determine solar

collector sizing, how plumbing will be

installed, whether we can use an existing

hot water tank, the optimum type of heat

exchanger, etc. Our typical site visit

takes about two to three hours, as we also

spend time reviewing the project &

technologies with you and answering your

questions.

After we gather this information,

Dovetail will develop a system designed

for your specific needs, and provide you

a detailed proposal and price

quotation.
