Sizing your pool — In most cases, solar pool heating will work for your pool. Measure your pool surface, then divide by panel size. Follow the 12 steps below. See the Worked Example below for a full example.
Step 1 — Header size: First, find out whether your system uses 2-inch or 1.5-inch headers. If you have more than 10 panels, we recommend 2-inch headers. If your plumbing is 1.5-inch, use a reducer. Schedule 40 black PVC is recommended.
Step 2 — Panel size: Panels are polypropylene, generally black, in 4x12, 4x10, and 4x8. You can mix and match, but keep rows the same size. Check your roof space. Headers are 50.75 inches. A rack design is available if your roof does not fit. Face south for 75 percent coverage; otherwise, consider 100 percent.
Step 3 — Pool surface area: Calculate your pool surface area in square feet. This is the starting point for how many panels you need.
Step 4 — How many panels: Divide the pool surface area (X) by the area of one panel. A 4x12 panel is 48 square feet, a 4x10 panel is 40 square feet, and a 4x8 panel is 32 square feet. More panels = a hotter pool. For a south-facing pool, 75 percent coverage is recommended. See the Worked Example chart for the full calculation.
Step 5 — Collector kit: Add one Collector Kit per panel. Each kit has 2 couplings and 4 hose clamps with screws, to connect the panels together.
Step 6 — System kit: Add one System Kit per system — only one per system. It has 2 CPVC grey adapters, plus 4 couplings and hose clamps with screws, for the feed and return connections.
Step 7 — Split kit: Add a Split Kit if your system has 2 rows, or if the headers are separated, for example where a vent blocks the run. It has 4 CPVC gray adapters, plus couplings, hose clamps, and screws.
Step 8 — Strapping: Strapping comes in 100-foot rolls, and it cannot be cut. Allow at least 15 feet per panel. For example, 140 feet needs 2 rolls.
Step 9 — Vacuum relief valve: Add a Vacuum Relief Valve at the highest point of the system, above the feed line. Specify whether your header is 2-inch or 1.5-inch. Note that if you have two sections in different areas, each section must have its own VR valve,
Step 10 — Divert water: Choose AUTOMATIC or MANUAL. AUTOMATIC uses a control box, an actuator, a 3-way valve, and 2 sensors — we recommend Goldline or Pentair. MANUAL uses a 3-way valve.
Step 11 — Check valves: Add check valves to prevent back wash. At least two check valves are needed per system.
Step 12 — Ball valves: Add ball valves to isolate parts of the system for service and to control flow.
Worked example — For a 400 sq ft pool using 4x12 panels at 48 sq ft each, 400 divided by 48 = about 8 panels for 100 percent coverage. For 75 percent coverage with south-facing panels, 8 x 0.75 = about 6 panels. Call 310-406-9371 or email solarsunpacific@gmail.com for pricing.

Solar Sun Pacific may update these terms, and the version in effect when you order applies. 2. Orders and pricing. Call for pricing. No prices are listed on this site. Prices are given by phone or by email at solarsunpacific@gmail.com, and are confirmed when you order. Sizes and availability may change without notice. Solar Sun Pacific may refuse or cancel an order in its discretion, including if it believes an order violates applicable law or is harmful to its interests. Solar Sun Pacific charges sales tax based on the applicable state rate and shipping location. 3. Payment. By phone or email only.

Normal shipping is 5 to 10 business days, but could be 2 to 3 weeks depending on seasonality and time of order. Panels are crated or in individual boxes. Shipping is mainland USA only. Florida pickup is available to save on shipping. If you are outside the mainland USA, notify Solar Sun Pacific before ordering for a shipping quote; otherwise a surcharge may apply. Do not use a P.O. Box as a delivery address, because some carriers will not deliver to a P.O. Box and the item will not ship. For damaged product, notify Solar Sun Pacific within 48 hours of delivery, check everything right after delivery, and keep accurate pictures and notes. Other problems must also be reported within 48 hours. 5. All sales final and returns. Strict no returns; all sales final. No changes when orders are finalized or processed. Because of panel size and high shipping charges, there are absolutely no returns. Contact Solar Sun Pacific with questions before ordering, and do not order until you have spoken to Solar Sun Pacific. If a return is ever authorized in writing by Solar Sun Pacific, shipping costs are not reimbursed, return shipping and surcharges are your cost, and a single 25 percent restocking/service fee is deducted from the total order amount before any refund. 6. Warranty. Contact the manufacturer direct, Techno-Solis only. Panels carry a 10-year warranty, are SRCC approved, and are Florida Solar Energy Center certified. Panels are not repairable, because repairs do not last, block channels, and reduce efficiency; an accepted warranty claim is for a replacement with a brand new whole panel, not repair. To qualify, install the panels as recommended by the manufacturer in the manual and warranty pamphlet received at purchase; otherwise there is no warranty. For a warranty claim, explain the problem to Techno-Solis, cut the 4 corners of the bad panel and send them to their plant, specify the panel size, and pay shipping of the new panels back to you. Use the warranty pamphlet, including its address and instructions, for what is and is not acceptable. You pay shipping for a warranty replacement. Other products are covered direct through their manufacturers. Neglecting installation, draining, and freeze-protection rules voids the warranty. 7. Installation. Installation is at your own risk. Solar Sun Pacific is not liable for damages caused by the panels, system, or installation, including roof leaks, water damage, property damage, damage to others' property, personal injury, or freeze damage, and is not responsible for installation damage. You must follow local codes and regulations, secure panels properly on a roof or rack as shown in the manufacturer manual to avoid roof leaks, get all plumbing leading up to the panels right, as plumbing leading up to the panels is your responsibility, and drain panels when not in use to avoid freeze damage. Solar Sun Pacific and its officers and employees are not responsible for damage during installation by you or anyone you hire. You indemnify and hold harmless Solar Sun Pacific and its officers and employees from claims, damages, and costs arising from installation, use, failure to follow recommendations, the manual, codes, or regulations, or damages caused by the panels or system. 8. Limitation of liability. To the fullest extent allowed by law, total liability for any claim from an order or product will not exceed the amount paid for that product. Solar Sun Pacific is not liable for indirect, incidental, punitive, or consequential damages, including lost profits, lost swim time, or costs of a replacement system, except where such a limit is not allowed by law. This section does not attempt to limit liability where the law does not allow it. 9. Governing law. Solar Sun Pacific is a South Carolina sole proprietorship. These terms are governed by the laws of South Carolina, without regard to conflict-of-law rules. Litigation is in the courts of South Carolina, or in diversity cases in the United States District Court for the District of South Carolina. Both parties waive trial by jury, to the extent allowed by law. 10. General. These terms are the entire agreement for website and phone or email orders.
