Solar Panel Packages in Dresden, TN

Is your roof ready to carry solar for the next twenty years?

That is the first question I ask about any solar project, and it surprises people, because they came to talk about panels. But panels are the easy part. They sit on the roof, and the roof sits on the house, and if the roof gives out before the panels do, you pay to take the whole system off and put it back.

I am Timothy Parks, and I put together solar panel packages for homeowners in Dresden and across Weakley County, Tennessee with the roof, the mounting and the layout at the center. My starting point is the building, because that is where my work is: roofs, framing, flashing and keeping water out.

This page explains what a solar package involves, how I judge whether a roof is suitable, how mounting and sealing work, what the utility side looks like in this part of Tennessee and what to ask anyone you talk to about solar. When you are ready to describe your home, use my phone line, (407) 383-9118.

What is a solar panel package?

A package is the set of components and work that turns sunlight on your roof into electricity in your house. It is more than the panels.

Different packages combine these pieces differently. A simple rooftop system without batteries is the most common. A system with batteries adds cost and complexity, and it makes sense for people who care about backup power. A ground-mounted array is another option for rural lots with room.

The electrical connection is specialist work. I do the roof side, the mounting and the weatherproofing, and where the authority requires a qualified tradesperson for the electrical side, that work is done by a qualified electrician under the applicable permits. I tell you how the pieces are divided before anything is signed or started.

How do I know whether a roof suits solar?

I look at six things before recommending anything.

1. Age and condition of the roof. Panels last a long time. If the roof beneath them is within a few years of replacement, the sensible move is to replace the roof first, or at the same time. Removing and reinstalling a solar array to re-roof is a hassle and an expense you can avoid.
2. Structure. Panels add weight and wind load. I check that rafters or trusses are sound, not sagging, cracked or showing water damage.
3. Orientation. In this hemisphere, south-facing slopes produce the most. East and west slopes still produce, with less output in total. North-facing slopes are rarely a good choice.
4. Shading. Trees, chimneys, neighboring buildings and even a vent stack can shade panels at different times of day. Shade on part of one panel can reduce a whole string, depending on the equipment.
5. Available space. Skylights, vents, valleys and chimneys reduce the usable area. Fire code setbacks around ridges and edges also limit where panels can go.
6. Roof type. Asphalt shingle, standing seam metal and exposed-fastener metal each take different mounting hardware. Tile and specialty roofs need extra care.

If the roof is not ready, I say so and explain what to fix first. The roof inspection page describes how I assess a roof, and the roof replacement page explains what happens when a new roof is the right first step. Putting solar on a worn roof means paying twice for roof work.

How are panels attached without causing leaks?

This is the part of solar that most worries me, and it is the part I know best. Every attachment point is a hole in your roof, and every hole is a potential leak if it is done carelessly.

On a shingle roof, each mount is fastened into a rafter, not just into the decking, with lag bolts or structural screws of the correct size and length. The mount sits on flashing that slides under the shingle above and over the shingle below, so water runs over it and not into it. Sealant is a backup, not the main defense. The goal is that the water-shedding layers stay intact around every penetration.

On standing seam metal, clamps grip the raised seams without penetrating the panels at all, which is why many people prefer this combination. On exposed-fastener metal, mounts are fastened into purlins or framing through the panel, with appropriate sealing and washers that need periodic checking.

Rails then connect the mounts, and panels clamp to the rails with a gap for airflow underneath. The airflow cools the panels and prevents debris and moisture from collecting against the roof.

I pay attention to the path of water. Panels can concentrate runoff at the lower edge and shed snow and ice in sheets in winter, so I consider what is below: walkways, doors, gutters and landscaping. Rails and wiring are kept away from valleys and places where debris builds up.

After installation, I check each mount and each flashing and take photographs of the finished attachments before panels cover them. Those photos are part of the record I give you.

What does weather in west Tennessee mean for solar?

Panels face the same weather your roof does, and a good installation accounts for it.

Wind. Spring storms bring strong straight-line winds. Mounts must be sized, spaced and fastened to resist uplift, and the array should sit inside the roof's edge zones. I follow the manufacturer's rules for attachment spacing and the load tables for the racking.

Hail. Panels are generally built to take hail of a certain size, but severe hail can still damage them. Ask about the panel's rated impact resistance and about the warranty terms. Hail that damages your shingles may damage your panels too, and a post-storm inspection of both is a good habit.

Heat. Panels lose some output when they get hot, and summer roofs get hot. Airflow beneath the array helps. Do not expect the same output in July that you would see on a cool, bright spring day.

Humidity and cloud. West Tennessee has a lot of humidity and a lot of partly cloudy days. Production varies through the year, and the winter months produce noticeably less than summer. Anyone who gives you a single annual output without explaining the seasonal swing is leaving something out.

Ice and snow. Winters here are mild compared with the northern states, but they can bring ice. Panels shed frozen precipitation in sheets. Keep walkways and gutters in mind.

Trees. Leaves and limbs fall on panels and shade them. Trimming or removing trees that shade the array may improve output. The tree removal page explains how I handle that.

How does the utility side work here?

This is the area where Tennessee differs most from places with strong statewide solar programs, and where you need to ask questions before you commit to anything.

Electric service in northwest Tennessee comes through local power companies and municipal systems, many of which buy their power wholesale from the Tennessee Valley Authority. The rules for connecting a home solar system, how you are credited for power you send back to the grid and what fees or approvals apply are set by your local power company and its supplier, and they are not the same as net metering rules elsewhere.

Because of that, I cannot tell you in advance what your utility will pay for the power you produce, and I do not want to guess. Before any package is designed, contact your local power company and ask:

• Do they allow grid-connected home solar, and what application process do they require?
• How are you credited for power you send to the grid, if at all?
• Are there interconnection fees, required equipment or inspections?
• Do they require a particular type of meter, disconnect or insurance document?
• Are there any programs or limits on system size?

Write down their answers and who gave them. If the value of exported power is low or uncertain, the design may favor producing for your own use during the day and sizing the system to your daytime load. That is a legitimate way to design, and I help you think it through.

I make no promises about savings. Your actual result depends on your consumption, the utility's rules, the weather and the equipment. Anyone who gives you a savings figure before looking at your bills and asking your utility is estimating without information.

Which electrical details should I understand?

I am not a substitute for a qualified electrician, and I do not describe electrical work as if I were one. But as the owner you should know the broad shape of what is involved.

The system has to connect to your home's electrical panel through a dedicated breaker and a disconnect. The panel needs enough room and enough capacity, and sometimes an older panel needs upgrading first. Wiring must be correctly sized, protected and grounded. Rapid shutdown devices are required in many installations so that firefighters can de-energize the roof wiring in an emergency.

Permits and inspections are part of the process. The authority having jurisdiction, which may be the city, the county or the utility, reviews the plans and inspects the installation. Do not accept an installation that skips this. An unpermitted system can cause trouble with the utility, with a future sale and with safety.

If you have an older home, I look at the main panel and the wiring in the attic or crawlspace during the assessment and flag anything that looks outdated. The 4 point inspection page describes how those older systems get documented.

What about batteries, ground mounts and outbuildings?

The rooftop system on the house is the standard package, but it is not the only shape solar takes in a rural county.

Batteries. A battery stores electricity for later, such as the evening or a power outage. Storms and ice bring outages here, and some owners want backup for a freezer, well pump or medical equipment. Batteries add cost, take wall or floor space and need careful placement, since they do not like extreme heat or cold. A grid-tied system without a battery usually shuts down when the grid goes down, as a safety measure for line workers, so panels alone will not keep the lights on in an outage. Ask about this directly if backup power matters to you.

Ground mounts. If your roof is shaded, facing the wrong way or too old, a ground-mounted array may make sense. It sits on posts or a frame in an open part of the lot, tilted at the best angle. It needs clear space, solid footings, protection from mowers and animals and a trench for the wiring back to the house. That is where my site preparation comes in. The site work page describes the grading, trenching and drainage that a ground array needs.

Barns, shops and garages. Large metal roofs on outbuildings can be good places for panels, with plenty of space and often a clear southern exposure. The structure has to carry the load, and the roof has to be in good condition. The metal buildings page covers those roofs in more detail.

Future-proofing. If you think you may add batteries or panels later, plan for it now. Leave room in the electrical panel, choose equipment that can expand and run conduit with room to spare. It costs little at the start and a lot to retrofit.

What is the process from first call to finished system?

Here is the order of events I follow.

1. Conversation. You tell me about your home, your electric bills and what you hope to get from solar. I ask about the roof's age and the shade.
2. Assessment. I visit, inspect the roof and attic, check the structure and measure the usable area. I photograph shade conditions and look at the electrical panel.
3. Utility questions. You or I contact your local power company about connection rules before anything is designed.
4. Design. I lay out the array, plan the mounting and the wire routing and describe the equipment. You see the plan and the roof details in plain terms.
5. Roof preparation. If the roof needs repair or replacement first, we do that first.
6. Permits and approvals. Plans are submitted where required and approvals are obtained before work begins.
7. Installation. Mounts are installed and flashed, rails and panels are set, wiring is run and the system is connected by the qualified electrician.
8. Inspection and activation. The inspector signs off, the utility approves and the system is turned on.
9. Record. You receive photos, equipment information, warranty paperwork and a plain explanation of how to read the monitoring.

I will tell you at the start that this process takes time, and that some of the waiting is on the utility and the permit office, not on me. I do not promise dates that depend on other people.

What should I ask before signing anything about solar?

Solar has a lot of promotion around it. These questions cut through the noise.

• What is the roof's condition, and how many more years should I expect from it?
• How are the panels attached, and where are the flashings?
• Who does the roof work, and who does the electrical work?
• What does my utility say about connection and credit for power I send back?
• What happens to the warranty on my roof if panels are installed?
• Who removes and reinstalls the panels if the roof needs work later?
• What will the system produce in winter, not just in summer?
• What permits are required and who handles them?
• What happens if a panel or inverter fails, and who services it?

Pay attention to how the answers are given. If a question about the roof gets a vague response, that tells you something. If a savings claim arrives without looking at your bills or asking about the utility, be careful.

I also encourage you to compare. Get more than one opinion, particularly on the roof side. If another provider recommends a different layout or a different roof approach, ask them why.

What about maintenance, storms and later roof work?

Solar is low-maintenance, not no-maintenance. A few habits keep a system healthy.

Rinse dust, pollen and bird droppings if production drops noticeably. Do not climb onto the roof to clean panels. Check the monitoring from time to time, and notice sudden drops. Have the roof inspected after severe storms, including the flashings under the array. Trim trees so shade does not creep in. Keep the area around the inverter clear.

If the roof beneath the array later needs repair, the panels in that area have to be removed and reinstalled by someone who knows how. This is another reason to start with a sound roof. The roof repair page describes leak repairs, and I coordinate any solar removal and reset with the electrician.
