From first calculation to a useful build record.
Choose where you are in your build. This guide explains the public tools and the features available to builder accounts, including existing members during launch preparation.
Start here
Visiting? Use the calculators without an account, browse public projects, and explore builder profiles. Registration availability is shown on the account page. While it is closed, you can confirm an email signup for launch news.
Already a member? Log in, open your dashboard, and choose a project or saved tool profile. Public calculators and saved account profiles serve different purposes: save a profile when you want to return to a plan later.
Plan with Builder Tools
- Battery Bank Sizing: list expected loads and use assumptions that reflect how often you run them. Review daily energy needs and battery capacity.
- Solar Sizing: use your energy requirement to explore solar capacity under the conditions you expect. Compare your available roof space and charging assumptions.
- Electrical Builder: examine circuits, cable runs, voltage drop, and wire-size choices.
For members, use each tool's save and manage controls to keep named planning profiles. Where offered, import from a saved profile or project, then review the imported values before saving. Changes in one plan do not mean every other saved plan has been recalculated.
These are planning estimates. Read the tool's assumptions and guidance and check component specifications before using a result in a build.
Create a project that makes sense
- Open My Projects and create your project.
- Choose its kind and type, describe the starting point and intended build, and set a realistic build status.
- Review its audience before sharing. Add the build areas you will use and begin documenting one area at a time.
- Use the project workspace to return to components, costs, journal entries, photos, and progress.
A title and a short description help visitors understand your goal. A journal entry explaining a decision can be useful even before the physical work begins.
Keep components, costs, and decisions together
The Component Registry describes products. Adding a component to your project records how it relates to your build. Review quantities, build area, status, and any installation details rather than assuming a catalog entry describes your installation.
Use cost entries for the amounts you want to track and review cost visibility before publishing. Use the journal to explain choices and the gallery to show progress. The project's activity and progress views help you return to recent work.
Choose what other people can see
Project visibility and profile visibility are separate controls. Public projects can be explored by visitors. Followers-only projects are limited to the applicable audience; private projects remain private. Review the current setting before sharing a link.
Profile settings let you choose Public, Members only, or Private, with directory and search-engine preferences where applicable. A public skill checkbox does not override your profile's audience. Cost visibility has its own controls.
Use a signed-out window to check the visitor experience after changing privacy settings.
Make your builder profile useful
In My Profile, use the separate About, Photos, Skills, Privacy, and Account sections. Each form saves separately, so save before switching sections.
Search the skills catalog, select relevant skills, choose a self-described experience level, and explicitly choose which ones to show. New selections start hidden. Move visible skills into your preferred order and check the preview before saving. Additional visible skills appear under More skills on your builder page.
Experience labels are self-described. A project on your profile does not automatically verify a particular skill.
Find builders and builds worth revisiting
Explore projects to compare shared builds. Members can use the available follow and saved-search tools to return to relevant projects and updates.
In the Builder Directory, search by name, handle, or public project title. Expand the skill browser, choose a category or minimum experience, and inspect matching skills on the result cards. Back to search results keeps your filters and page.
For a public project, use its share controls to prepare a link and introduction. Always review what is public before posting elsewhere.
Keep progress honest
Update build-area progress and project status as work changes. Use the completion workflow when the project is ready, and keep documenting later improvements. A completed build can still be a useful record of the choices that led to it.
Public profiles show public project examples and let visitors page through them. Private work is not included in those public counts.
