Solar-Ready Electrical Preparation for Colorado Homes
Panel capacity, busbar headroom and pre-piping so a future solar or battery installation lands on a service that can actually accept it.
Why solar quotes stall at the panel
Solar interconnection has to obey the busbar rating in your existing panel. A 100-amp panel, a full busbar, or a main breaker that leaves no headroom for backfeed will hold up a solar installation no matter how good the array design is. Homeowners usually discover this after the solar contract is signed, which is the expensive order to find out.
Getting the electrical side ready first turns the solar install into a clean, fast job. It also means you are choosing your panel work on its own merits, at a price you compared, rather than as a rushed change order inside somebody else's contract.
- 100-amp services that cannot accept a meaningful backfeed
- Panels with no remaining breaker spaces for a solar disconnect
- Busbar ratings that fail the interconnection calculation
- Older equipment a solar installer will not tie into
- Battery plans that need a protected loads subpanel
What solar-ready preparation includes
We run a load calculation, confirm what your service can accept, and lay out the work: a panel or service upgrade if the busbar cannot carry the backfeed, breaker space and a properly rated disconnect location, grounding brought current, and conduit pre-piped from the panel to the inverter or roof penetration point while walls or attics are accessible.
Where a battery is on the horizon, we plan for the protected-loads subpanel now, because retrofitting one later means opening the same walls twice.
- Panel or service upgrade sized for planned backfeed
- Breaker space and disconnect location planned to code
- Conduit and pull strings run to the inverter or array location
- Grounding and bonding verified and corrected
- Battery and protected-loads planning where relevant
What we do and what we do not
We prepare the electrical service. We do not sell, design or install solar arrays, and we are not paid by anyone who does. That independence is the point: our recommendation on your panel is not shaped by a solar sale, so if your service is already fine for the array you are considering, we will simply tell you that.
Our process
How an EPO solar-ready prep job runs
- 01
Talk through the solar plan
Array size, inverter type and whether a battery is in scope all change the electrical answer.
- 02
Load calculation and panel review
We check busbar rating, main breaker, breaker spaces and grounding against the interconnection math.
- 03
Written scope and price
Only the work the plan actually requires, priced fixed and in writing.
- 04
Permitted preparation work
Upgrade, breaker space, disconnect provision and conduit pre-piping completed and inspected.
- 05
Hand-off
You get the panel details and photos your solar installer will ask for.
Pricing
What moves the price on this job
We quote after seeing the equipment, because these details change the number more than anything else.
- Whether a service upgrade is required for the backfeed
- Distance and route from the panel to the inverter location
- Battery and protected-loads subpanel scope
- Grounding electrode corrections on older homes
- Permit and inspection fees
Monthly payments available through Hearth
Prequalifying takes about a minute and uses a soft credit check, so seeing your options does not affect your credit score.
FAQ
Common questions
Do I need a 200-amp service for solar?
Not always. It depends on your array size, your busbar rating and the interconnection method. Plenty of well-sized 200-amp panels take solar with no work at all, and some 100-amp services can with a smaller array or a supply-side connection.
Should I upgrade before or after signing a solar contract?
Before, if you can. Knowing your electrical scope up front keeps it out of the solar change-order process and lets you compare prices calmly.
Do you install solar panels?
No. We handle the panel, service and conduit preparation, and we work alongside whichever solar contractor you choose.
What is pre-piping?
Running the conduit, and often a pull string, from the panel to where the inverter or array will land, while the path is still accessible. It saves opening finished walls later.
Can you prepare for a battery too?
Yes. Batteries usually need a protected-loads subpanel and a specific interconnection arrangement, and planning that now is much cheaper than retrofitting it.
Still deciding?
The fastest way to get a real answer for your home is to have a tech open the panel. The on-site estimate is free, and you leave with a written price for solar-ready prep.
