Sedna Aire USA
Solar-Assisted Air Conditioning by Sedna Aire USA
Solar 4 Sarasota is your source for Sedna Aire USA solar-assisted air conditioning equipment in Sarasota and Manatee Counties. After years of exhaustive testing and evaluation the technology has been proven to meet or exceed early claims of efficiency. The use of solar thermal energy is the first major innovation in air conditioning technology since… well, EVER!!!
Some companies claim to offer “solar” air conditioning, but they utilize photo-voltaic panels to power the compressor. That’s good, I guess. But, what if you could eliminate the compressor all together? During the hot, sunny hours of the day that’s exactly what Sedna Aire USA systems do. And, the savings can exceed 58%. The efficiency rating can be 32 SEER or more.
In Florida especially, this really makes sense because THE HOTTER IT GETS, THE BETTER IT WORKS!
FPL is currently pre-approving rebates for customers who plan to install grid-tied PV systems. Details can be found
HERE.
Here at Solar4Sarasota, we encourage all Florida residents and FPL customers to take advantage of this program. Recommendations regarding vendors, sizing and equipment options are available by calling 941-321-3177.
Here’s what FPL has to say about the program:
“As part of a five-year pilot program authorized by the Florida Public Service Commission, this rebate is available to all existing FPL residential customers in existing dwellings. The rebates are not available for new construction or PV systems that are already installed. Applicants must be current account holders of the premise where the solar photovoltaic system is being installed.
The Residential PV rebate is for solar electric panels, mounting hardware, grid-interactive electric inverter(s), optional battery systems, associated cabling, and for systems over 10 kilowatt AC, disconnect devices. This rebate program is only for grid-interactive PV systems with a minimum nameplate rating of 2 kilowatts direct current (DC) and a maximum nameplate rating of 2 megawatts. All components must be tested and listed by a nationally recognized testing and certification laboratory for continuous interactive operation with an electric distribution system in compliance with the applicable codes and standards of IEEE 1547, IEEE 1547.1, and UL 1741. All products installed must be new, not refurbished or previously installed.
Customers should choose products and contractors carefully, given the many variables involved. The customer is solely responsible for selecting, hiring and managing the contractor who will install the eligible solar products. FPL bears no responsibility for the quality or performance of any products or contractors chosen by the customer.”
By “Super Heating” the refrigerant with the aid of the Solar Collector, we are able to increase the temperature difference between the condenser coil and the ambient temperature. By creating this difference, Sedna Aire is able to utilize the entire coil face at the condenser which allows for a better heat exchange throughout the entire system.
With a greater heat exchange, Sedna Aire is able to not only reduce the temperature in the conditioned space but also maintain better humidity control which makes the space more comfortable at a higher temperature…in addition your air conditioning unit doesn’t run as long and cycles less.

With the combination of the solar heat and changing the thermodynamic process of the refrigerant, Sedna Aire is able to reduce the required work of the compression operation of the compressor. This then lowers the required electrical consumption, reduces the running time of the entire system and maintains a more comfortable conditioned space.
Hate to watch that water flow down the drain while waiting for it to get hot? Many houses utilize circulation loops that cycle the water through the pipes, keeping hot water near the faucets. Those systems require a “return loop” pipe, typically a 1/2″ line from the farthest point of use. These return lines are frequently installed in new construction.
But, what about existing homes? Now there’s an answer: the Watts Premier Hot Water Re-circulating System.
This short article describes the operation of OPEN LOOP CIRCULATION TYPE DOMESTIC WATER-HEATERS.
Your Solar Water-Heater
Your home is equipped with an “open loop solar water heating system.” This system is composed of the collector panel, a large capacity storage tank and a DC circulation pump. The pump is powered by a photo-voltaic (PV) panel which is oriented the same as the collector array.
When the Sun is Shining…
The PV panel makes electricity that powers the pump. The pump draws the water out of the bottom of the storage tank, circulates it through the collector panels and returns it to the tank. The more direct the sunlight (striking the panels at right angles), the better the systems works.
In general, we attempt to orient the collector panels facing south at an angle of 18 degrees. Flat is OK.

When the Sun isn’t Shining…
The system doesn’t work. Electric elements in the storage tank will heat the water used at night or during cloudy hours. On foul weather days, the solar system may act as a pre-heater, raising the ambient temperature of the water a few degrees.
No Actions…
Are required on your part. When it is beneficial for water to circulate through the collectors, the pump will operate. When it isn’t, it won’t.
